Integrated Ceramic Packaging for Implantable Hearing Devices
Cochlear implants have transformed the treatment of severe hearing loss and continue to evolve toward smaller, more connected, and increasingly sophisticated implantable systems.
As manufacturers develop next-generation hearing technologies, ceramic packaging plays an increasingly important role by combining long-term hermeticity, miniaturization, wireless functionality, and mechanical reliability.
SCT partners with leading hearing implant manufacturers to develop integrated ceramic packaging solutions, combining ceramic casings and hermetic feedthroughs to support the next generation of implantable hearing devices.

06 – FAQ
Frequently Asked Questions
Why are ceramic casings used in cochlear and hearing implants?
Ceramic casings provide long-term hermeticity while remaining biocompatible and transparent to radio-frequency (RF) signals. Unlike metallic housings, ceramics allow wireless communication without compromising the protection of the implant’s sensitive electronics.
SCT develops customized ceramic casings that combine hermeticity, miniaturization, and RF performance to support the next generation of implantable hearing devices.
Why combine the ceramic casing and hermetic feedthrough?
The ceramic casing and hermetic feedthrough form a single packaging system. Developing both components together helps ensure precise alignment, optimized hermetic sealing, and improved mechanical integration.
By designing and manufacturing both the ceramic casing and the feedthrough, SCT simplifies integration, reduces development risks, and helps optimize the overall performance of the implant.
What is inductive power transfer?
Inductive power transfer allows energy to be transmitted wirelessly between an external device and an implanted system using electromagnetic fields. This technology is becoming increasingly important as manufacturers develop smaller and more sophisticated implantable hearing devices.
SCT develops ceramic packaging solutions that support inductive power transfer while protecting sensitive electronics through robust hermetic sealing.
Why is hermeticity so important for implantable hearing devices?
Implantable electronics must remain protected from body fluids throughout the lifetime of the device. Even microscopic leaks can compromise the performance and reliability of sensitive electronic components.
SCT has decades of experience developing hermetic ceramic-to-metal assemblies that help manufacturers achieve the long-term reliability expected from implantable medical devices.
How does ceramic packaging support miniaturization?
As hearing implants become smaller, engineers must integrate more functionality into increasingly compact devices while maintaining reliability and wireless performance.
SCT works closely with customers to co-develop compact ceramic casings and hermetic feedthroughs that support miniaturization without compromising manufacturability or long-term performance.

Developing the Next Generation of Hearing Implants?
Whether you’re developing a cochlear implant, a middle ear implant, or another implantable hearing technology, SCT can help transform your technical requirements into robust, integrated ceramic packaging solutions.
How do ceramics support wireless communication?
Modern hearing implants rely on wireless communication to exchange data with external devices and clinicians. Ceramic materials are naturally transparent to radio-frequency (RF) signals, allowing reliable data transmission without sacrificing mechanical strength or hermeticity.
SCT develops ceramic packaging solutions that support RF transparency while maintaining the long-term reliability required for implantable medical devices.
