F: Massimo, vielen Dank, dass Sie heute bei uns sind. K\u00f6nnten Sie zu Beginn Ihren beruflichen Hintergrund und Ihre heutige Rolle bei Servotecnica beschreiben?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Ich bin 2001 als Elektroingenieur zu Servotecnica gekommen und habe zun\u00e4chst in der technischen Abteilung gearbeitet, mit Schwerpunkt auf Antriebsprogrammierung und Steuerelektronik f\u00fcr Bewegungsachsen. Diese fr\u00fche Phase hat mir ein starkes Verst\u00e4ndnis daf\u00fcr vermittelt, wie sich reale Maschinen tats\u00e4chlich verhalten \u2013 und nicht nur, wie sie auf dem Papier funktionieren sollen.<\/p>\n\n\n\n

Im Laufe der Zeit habe ich zudem eng mit Kunden auf der kommerziellen und anwendungstechnischen Seite zusammengearbeitet. Diese Kombination war \u00e4u\u00dferst wertvoll, da sie es mir erm\u00f6glichte, reale Betriebsanforderungen in praxisnahe technische L\u00f6sungen zu \u00fcbersetzen, die langfristig zuverl\u00e4ssig funktionieren.<\/p>\n\n\n\n

In den letzten Jahren bin ich vollst\u00e4ndig in eine technische F\u00fchrungsrolle als Technischer Direktor zur\u00fcckgekehrt. Dabei war ich intensiv an der Neuorganisation der technischen Abteilung, dem Aufbau einer st\u00e4rkeren Forschungs- und Entwicklungsstruktur sowie der Verbesserung unserer Unterst\u00fctzung bei komplexen, sicherheitskritischen Anwendungen beteiligt. Gerade in medizinischen Systemen gibt es keinerlei Spielraum f\u00fcr \u00dcberraschungen \u2013 hier sind technische Disziplin und Validierung ebenso wichtig wie reine Leistungsdaten.<\/p>\n\n\n\n

F: Mit welcher Denkweise gehen Sie als Technischer Direktor an medizinische Anwendungen heran?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Ich betrachte medizinische Projekte immer als Gesamtsysteme und nicht als einzelne Komponenten. Ein Schleifring ist niemals nur ein Bauteil zur Strom\u00fcbertragung. Er befindet sich an der Schnittstelle zwischen Mechanik, Elektronik, Datenintegrit\u00e4t und langfristiger Zuverl\u00e4ssigkeit.<\/p>\n\n\n\n

In chirurgischen Robotern und modernen Diagnosesystemen ist der Schleifring h\u00e4ufig der zentrale \u00dcbertragungspfad f\u00fcr Energie, Signale und Hochgeschwindigkeitsdaten \u00fcber rotierende Schnittstellen. Jede Verschlechterung wirkt sich sofort auf das Gesamtsystem aus.<\/p>\n\n\n\n

Deshalb geht es nicht darum, maximale Katalogwerte zu erreichen, sondern um langfristig stabiles Verhalten. Das umfasst vorhersehbare elektrische Kontaktperformance, konstantes Drehmoment, kontrollierten Verschlei\u00df, saubere Signal\u00fcbertragung sowie Pr\u00fcfkonzepte, die dem Risikoprofil und den regulatorischen Anforderungen der Kunden entsprechen.<\/p>\n\n\n\n

F: Sterilisation und Reinigung spielen im medizinischen Design eine gro\u00dfe Rolle. Wie beeinflusst das die Schleifringentwicklung?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Der erste Schritt besteht darin, realistisch zu verstehen, welchen Belastungen das Ger\u00e4t \u00fcber seine Lebensdauer hinweg ausgesetzt ist.<\/p>\n\n\n\n

Manche Systeme durchlaufen Hochtemperatur-Sterilisationszyklen, andere chemische Desinfektion, viele werden regelm\u00e4\u00dfig mit aggressiven Reinigungsmitteln behandelt. Jede Umgebung wirkt unterschiedlich auf Metalle, Kunststoffe, Dichtungen und Schmierstoffe.<\/p>\n\n\n\n

Auch wenn der Schleifring selbst nicht direkt sterilisiert wird, m\u00fcssen Feuchtigkeitseintritt, Chemikalienexposition und langfristige Materialvertr\u00e4glichkeit ber\u00fccksichtigt werden.<\/p>\n\n\n\n

Technisch bedeutet das eine sorgf\u00e4ltige Materialauswahl, durchdachte Dichtungskonzepte und realistische Lebensdauertests. Es ist deutlich besser, von Anfang an f\u00fcr die reale Umgebung zu konstruieren, als sich allein auf das Geh\u00e4use zu verlassen.<\/p>\n\n\n\n

F: Wo beginnen Sie, wenn ein Kunde nach dem \u201eperfekten medizinischen Schleifring\u201c fragt?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Wir starten immer mit einer strukturierten Anforderungsanalyse. Medizinische Projekte enthalten oft versteckte Randbedingungen wie Datensensibilit\u00e4t, Reinigungsprozesse, Drehmomentgrenzen oder Dokumentationspflichten.<\/p>\n\n\n\n

Sobald diese klar sind, konzentriert sich das Design auf f\u00fcnf Kernbereiche: Kontakttechnologie und Materialien, elektrische Architektur, mechanisches Verhalten, Umweltschutz und Fertigbarkeit.<\/p>\n\n\n\n

Diese Faktoren beeinflussen sich gegenseitig stark. Schon kleine \u00c4nderungen an Steckverbindern oder Kanalzahlen k\u00f6nnen Auswirkungen auf Abdichtung, EMV, Drehmoment oder Montage haben. Deshalb ist fr\u00fche Zusammenarbeit entscheidend.<\/p>\n\n\n\n

F: Welche Rolle spielen Materialien und Kontaktsysteme f\u00fcr die Zuverl\u00e4ssigkeit in medizinischen Anwendungen?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Sie sind absolut zentral.<\/p>\n\n\n\n

F\u00fcr empfindliche Signale und lange Lebensdauer m\u00fcssen Kontaktsysteme elektrisches Rauschen und Verschlei\u00df minimieren. H\u00e4ufig kommen Edelmetallkontakte, Mehrfaserb\u00fcrstensysteme und pr\u00e4zise Oberfl\u00e4chenbehandlungen zum Einsatz.<\/p>\n\n\n\n

Das Verschlei\u00dfverhalten beeinflusst nicht nur die Lebensdauer, sondern auch die Stabilit\u00e4t. Leistungsverlust, Partikelbildung oder Kontaktunterbrechungen sind in medizinischen Systemen nicht akzeptabel.<\/p>\n\n\n\n

Durch optimierte Kontaktgeometrien und Materialpaarungen lassen sich extrem stabile elektrische Eigenschaften erreichen und die Lebensdauer deutlich verl\u00e4ngern.<\/p>\n\n\n\n

F: Die Signalintegrit\u00e4t wird immer wichtiger. Wie sichern Sie diese \u00fcber rotierende Schnittstellen?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Entscheidend ist, den Schleifring als gemischtes Signalsystem zu betrachten \u2013 nicht als Sammlung einzelner Stromkreise.<\/p>\n\n\n\n

Leistungskan\u00e4le, analoge Sensorleitungen, digitale Steuersignale und Hochgeschwindigkeitsdaten werden gezielt angeordnet. Abschirmung, Erdung und physikalische Trennung sind von Anfang an Teil des Designs.<\/p>\n\n\n\n

Ziel ist es, dass sich der Schleifring m\u00f6glichst wie ein hochwertiges Kabel verh\u00e4lt, w\u00e4hrend St\u00f6rungen durch bewegliche Kontakte aktiv minimiert werden.<\/p>\n\n\n\n

F: Medizinische Kunden ben\u00f6tigen h\u00e4ufig kundenspezifische L\u00f6sungen. Wie bleibt die Fertigung dabei beherrschbar?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Wir setzen auf modulare Designs auf Basis bew\u00e4hrter Plattformen.<\/p>\n\n\n\n

Statt jedes Projekt neu zu entwickeln, passen wir bestehende Architekturen an \u2013 durch \u00c4nderungen bei Kanalzahl, Materialien, Steckverbindern, Abdichtung und Layout. Das gew\u00e4hrleistet hohe Qualit\u00e4t bei gleichzeitig gro\u00dfer Flexibilit\u00e4t.<\/p>\n\n\n\n

Gerade im medizinischen Bereich k\u00f6nnen kleine Anpassungen gro\u00dfe Auswirkungen haben, daher ist kontrollierte Individualisierung mit konsequenter Pr\u00fcfung entscheidend.<\/p>\n\n\n\n

F: K\u00f6nnen Sie ein erfolgreiches medizinisches Projektbeispiel nennen?
<\/strong><\/h3>\n\n\n\n

A:<\/strong> Ein gutes Beispiel war ein Kunde aus der histologischen Analyse, bei der Gewebeproben vor der mikroskopischen Untersuchung pr\u00e4zise temperiert werden m\u00fcssen. Schon kleinste Temperaturschwankungen beeinflussen die Analysequalit\u00e4t.<\/p>\n\n\n\n

Der gr\u00f6\u00dfte Engpass war der verf\u00fcgbare Bauraum. Trotz minimalem Platzbedarf mussten sowohl Heizleistung als auch Sensordaten zuverl\u00e4ssig \u00fcbertragen werden.<\/p>\n\n\n\n

Wir entwickelten extrem flache Pancake-Schleifringe f\u00fcr kompakte Baugruppen. Zwei Einheiten mit jeweils vier Kan\u00e4len \u2013 zwei f\u00fcr Leistung, zwei f\u00fcr Signale \u2013 wurden integriert.<\/p>\n\n\n\n

Trotz der geringen Bauh\u00f6he lieferten sie stabile elektrische Performance und erm\u00f6glichten pr\u00e4zise Temperaturregelung. Gleichzeitig erf\u00fcllten sie s\u00e4mtliche Anforderungen an Testbarkeit und R\u00fcckverfolgbarkeit.<\/p>\n\n\n\n

Das ultraflache Design passte perfekt in das Ger\u00e4t und gew\u00e4hrleistete langfristige Zuverl\u00e4ssigkeit ohne zus\u00e4tzliche Systemkomplexit\u00e4t.<\/p>\n","protected":false},"excerpt":{"rendered":"

To start, could you describe your background and what you do at Servotecnica today? A: I joined Servotecnica in 2001 as an electrical engineer and began in the technical department working on drive programming and control electronics for motion axes. That early phase gave me a strong grounding in how real machines behave, not just how they are supposed to behave on paper. Over time, I also gained experience working closely with customers on the commercial and application side. That combination turned out to be extremely valuable because it helped me translate real operating constraints into engineering decisions that actually work long term in the field. In recent years I returned fully to a technical leadership role as Technical Director. I have been deeply involved in reorganising the technical department, developing a stronger research and development structure, and improving how we support customers on complex, mission critical applications. In medical systems especially, there is no tolerance for surprises, so engineering discipline and validation become just as important as performance. Q: When you look at medical applications, what mindset do you bring as Technical Director? A: I approach medical projects as full systems rather than individual components. A slip ring is never just something that passes current from one side to the other. It sits at the intersection of mechanics, electronics, data integrity, and long term reliability. In surgical robots and advanced diagnostic machines, the slip ring often becomes the single pathway through which all power, signals, and high speed data must pass across rotating joints. If something degrades there, it shows up immediately at the system level. Because of that, the mindset is not about chasing maximum catalogue specifications. It is about designing stable behaviour over time. That means predictable electrical contact performance, consistent torque, controlled wear, clean signal transmission, and a test strategy that matches the customer\u2019s risk profile and regulatory expectations. Q: Sterilisation and cleaning often come up in medical design. How does that affect slip ring engineering in practice? A: The first step is understanding what the device will realistically be exposed to throughout its life. Some systems involve high temperature sterilisation cycles, others involve chemical disinfection, and many involve frequent cleaning with aggressive agents. Each of these environments has different effects on metals, polymers, seals, and lubricants. Even when the slip ring is not directly sterilised, the device architecture must still consider moisture ingress, chemical exposure, and long term material compatibility. From an engineering perspective, this becomes a combination of material selection, sealing strategy, and realistic life testing. It is far better to design for the actual environment from the start than to assume the enclosure will solve everything. Q: When a customer asks for \u201cthe perfect medical slip ring,\u201d where do you begin? A: We always start with a structured requirements discussion. Medical projects often hide constraints that are not obvious at first, such as data sensitivity, cleaning exposure, torque limits, or regulatory documentation needs. Once those are clear, the design naturally focuses on five core areas: contact technology and materials, electrical architecture, mechanical behaviour, environmental protection, and manufacturability. All of these interact. A small change in connector type or channel count can influence sealing, EMC performance, torque, and even assembly methods. That is why early collaboration is so important. Q: What role do materials and contact systems play in medical reliability? A: They are central. For sensitive signals and long service life, the contact system must minimise electrical noise and wear. Precious metal contact technologies, multi fibre brush systems, and carefully controlled surface finishes are often used to achieve this. Wear behaviour matters not just for lifetime but also for stability. Performance drift, debris generation, or intermittent contact are unacceptable in medical platforms designed for continuous operation over many years. By optimising contact geometry and material pairing, it is possible to achieve extremely smooth electrical behaviour while extending operational life significantly compared with older brush technologies. Q: Signal integrity seems increasingly important in modern medical devices. How do you protect it across a rotating interface? A: The key is to treat the slip ring as a mixed signal system rather than a collection of independent circuits. Power channels, analogue sensing lines, digital control signals, and high speed data must be laid out intentionally. Shielding, grounding strategy, and physical separation are designed into the internal architecture from the beginning. The goal is to make the slip ring behave as closely as possible to a high quality cable, while actively minimising the disturbances introduced by moving electrical contacts. Q: Medical customers often need custom solutions. How do you keep those manufacturable? A: We rely on modular design built on a wide base of proven standard architectures. Rather than designing from scratch every time, we adapt existing platforms by modifying channel count, materials, connectors, sealing, and layout. This keeps quality consistent while allowing high levels of customisation. In medical projects, even small changes can cascade into multiple engineering areas, so controlled customisation with strong testing discipline is essential. Q: Could you share an example of a medical slip ring project and what made it successful? A: One good example came from a customer developing precision equipment for histological analysis, where tissue samples must be heated and stabilised before microscopic examination. The temperature control in this process is critical, as even small fluctuations can affect the quality of the analysis. The main challenge was space. The device design left very little room for additional components, but it still required reliable transmission of both power for the heating elements and signal lines for temperature sensors. We developed a custom solution using ultra flat pancake style slip rings designed specifically for compact assemblies. Two units were integrated into the system, each with four channels, two for power and two for signal transmission, with current capacity suitable for the heating process. Despite their very low profile, the slip rings delivered stable electrical performance and allowed precise temperature control throughout operation. Just as importantly, the solution supported full testing and traceability, which is essential in medical equipment. The ultra flat design fit seamlessly into the device while providing long term reliability, enabling the customer to maintain consistent performance without increasing the size or complexity of the system.\"},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/servotecnica.com\/de\/servotecnica-slip-ring-spotlights-entwicklung-des-perfekten-schleifrings-fuer-medizinische-anwendungen-mit-massimo-redaelli\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\/\/servotecnica.com\/de\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Servotecnica Slip Ring Spotlights: Entwicklung des perfekten Schleifrings f\u00fcr medizinische Anwendungen mit Massimo Redaelli\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\/\/servotecnica.com\/de\/#website\",\"url\":\"https:\/\/servotecnica.com\/de\/\",\"name\":\"Servotecnica\",\"description\":\"Servotecnica\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":{\"@type\":\"EntryPoint\",\"urlTemplate\":\"https:\/\/servotecnica.com\/de\/?s={search_term_string}\"},\"query-input\":{\"@type\":\"PropertyValueSpecification\",\"valueRequired\":true,\"valueName\":\"search_term_string\"}}],\"inLanguage\":\"de\"},{\"@type\":\"Person\",\"@id\":\"https:\/\/servotecnica.com\/de\/#\/schema\/person\/408c4f3086f9f1bdcdb927497cc83f5a\",\"name\":\"Servotecnica\",\"image\":{\"@type\":\"ImageObject\",\"inLanguage\":\"de\",\"@id\":\"https:\/\/servotecnica.com\/de\/#\/schema\/person\/image\/\",\"url\":\"https:\/\/secure.gravatar.com\/avatar\/718e843be741239bfe18d39bc81e410e348189cb6a82687c12d3d76aa031836b?s=96&d=mm&r=g\",\"contentUrl\":\"https:\/\/secure.gravatar.com\/avatar\/718e843be741239bfe18d39bc81e410e348189cb6a82687c12d3d76aa031836b?s=96&d=mm&r=g\",\"caption\":\"Servotecnica\"},\"sameAs\":[\"https:\/\/servotecnica.com\"]}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Servotecnica Slip Ring Spotlights: Entwicklung des perfekten Schleifrings f\u00fcr medizinische Anwendungen mit Massimo Redaelli -

Q: When you look at medical applications, what mindset do you bring as Technical Director? A: I approach medical projects as full systems rather than individual components. A slip ring is never just something that passes current from one side to the other. It sits at the intersection of mechanics, electronics, data integrity, and long term reliability. In surgical robots and advanced diagnostic machines, the slip ring often becomes the single pathway through which all power, signals, and high speed data must pass across rotating joints. If something degrades there, it shows up immediately at the system level. Because of that, the mindset is not about chasing maximum catalogue specifications. It is about designing stable behaviour over time. That means predictable electrical contact performance, consistent torque, controlled wear, clean signal transmission, and a test strategy that matches the customer\u2019s risk profile and regulatory expectations. Q: Sterilisation and cleaning often come up in medical design. How does that affect slip ring engineering in practice? A: The first step is understanding what the device will realistically be exposed to throughout its life. Some systems involve high temperature sterilisation cycles, others involve chemical disinfection, and many involve frequent cleaning with aggressive agents. Each of these environments has different effects on metals, polymers, seals, and lubricants. Even when the slip ring is not directly sterilised, the device architecture must still consider moisture ingress, chemical exposure, and long term material compatibility. From an engineering perspective, this becomes a combination of material selection, sealing strategy, and realistic life testing. It is far better to design for the actual environment from the start than to assume the enclosure will solve everything. Q: When a customer asks for \u201cthe perfect medical slip ring,\u201d where do you begin? A: We always start with a structured requirements discussion. Medical projects often hide constraints that are not obvious at first, such as data sensitivity, cleaning exposure, torque limits, or regulatory documentation needs. Once those are clear, the design naturally focuses on five core areas: contact technology and materials, electrical architecture, mechanical behaviour, environmental protection, and manufacturability. All of these interact. A small change in connector type or channel count can influence sealing, EMC performance, torque, and even assembly methods. That is why early collaboration is so important. Q: What role do materials and contact systems play in medical reliability? A: They are central. For sensitive signals and long service life, the contact system must minimise electrical noise and wear. Precious metal contact technologies, multi fibre brush systems, and carefully controlled surface finishes are often used to achieve this. Wear behaviour matters not just for lifetime but also for stability. Performance drift, debris generation, or intermittent contact are unacceptable in medical platforms designed for continuous operation over many years. By optimising contact geometry and material pairing, it is possible to achieve extremely smooth electrical behaviour while extending operational life significantly compared with older brush technologies. Q: Signal integrity seems increasingly important in modern medical devices. How do you protect it across a rotating interface? A: The key is to treat the slip ring as a mixed signal system rather than a collection of independent circuits. Power channels, analogue sensing lines, digital control signals, and high speed data must be laid out intentionally. Shielding, grounding strategy, and physical separation are designed into the internal architecture from the beginning. The goal is to make the slip ring behave as closely as possible to a high quality cable, while actively minimising the disturbances introduced by moving electrical contacts. Q: Medical customers often need custom solutions. How do you keep those manufacturable? A: We rely on modular design built on a wide base of proven standard architectures. Rather than designing from scratch every time, we adapt existing platforms by modifying channel count, materials, connectors, sealing, and layout. This keeps quality consistent while allowing high levels of customisation. In medical projects, even small changes can cascade into multiple engineering areas, so controlled customisation with strong testing discipline is essential. Q: Could you share an example of a medical slip ring project and what made it successful? A: One good example came from a customer developing precision equipment for histological analysis, where tissue samples must be heated and stabilised before microscopic examination. The temperature control in this process is critical, as even small fluctuations can affect the quality of the analysis. The main challenge was space. The device design left very little room for additional components, but it still required reliable transmission of both power for the heating elements and signal lines for temperature sensors. We developed a custom solution using ultra flat pancake style slip rings designed specifically for compact assemblies. Two units were integrated into the system, each with four channels, two for power and two for signal transmission, with current capacity suitable for the heating process. Despite their very low profile, the slip rings delivered stable electrical performance and allowed precise temperature control throughout operation. Just as importantly, the solution supported full testing and traceability, which is essential in medical equipment. The ultra flat design fit seamlessly into the device while providing long term reliability, enabling the customer to maintain consistent performance without increasing the size or complexity of the system."},{"@type":"BreadcrumbList","@id":"https:\/\/servotecnica.com\/de\/servotecnica-slip-ring-spotlights-entwicklung-des-perfekten-schleifrings-fuer-medizinische-anwendungen-mit-massimo-redaelli\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/servotecnica.com\/de\/"},{"@type":"ListItem","position":2,"name":"Servotecnica Slip Ring Spotlights: Entwicklung des perfekten Schleifrings f\u00fcr medizinische Anwendungen mit Massimo Redaelli"}]},{"@type":"WebSite","@id":"https:\/\/servotecnica.com\/de\/#website","url":"https:\/\/servotecnica.com\/de\/","name":"Servotecnica","description":"Servotecnica","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/servotecnica.com\/de\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"de"},{"@type":"Person","@id":"https:\/\/servotecnica.com\/de\/#\/schema\/person\/408c4f3086f9f1bdcdb927497cc83f5a","name":"Servotecnica","image":{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/servotecnica.com\/de\/#\/schema\/person\/image\/","url":"https:\/\/secure.gravatar.com\/avatar\/718e843be741239bfe18d39bc81e410e348189cb6a82687c12d3d76aa031836b?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/718e843be741239bfe18d39bc81e410e348189cb6a82687c12d3d76aa031836b?s=96&d=mm&r=g","caption":"Servotecnica"},"sameAs":["https:\/\/servotecnica.com"]}]}},"_links":{"self":[{"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/posts\/15932","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/comments?post=15932"}],"version-history":[{"count":3,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/posts\/15932\/revisions"}],"predecessor-version":[{"id":15941,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/posts\/15932\/revisions\/15941"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/media\/15929"}],"wp:attachment":[{"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/media?parent=15932"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/categories?post=15932"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/servotecnica.com\/de\/wp-json\/wp\/v2\/tags?post=15932"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
