Seamless Ceramics for Biomedical Applications

Tech ID: 32364 / UC Case 2015-938-0

Background

A basic requirement for implantable biomedical devices is long-term biocompatibility of the packaging materials and leakproof, hermetic seals. Today’s implant seals are based on sealing dissimilar materials (for example, ceramic-metal) using materials with inferior biocompatibility and mechanical strength. There is a need to create seamless ceramic packages for encapsulating hermetically enclosed electronics that are biocompatible.  Such packages are useful for medical device applications.

Brief Description

Prof. Guillermo Aguilar-Mendoza and his colleagues from the University of California, Riverside (UCR) and Prof. Javier Garay and his colleagues from the University of California, San Diego have developed an all ceramic, biocompatible, hermetically sealed package for encapsulating electronics. This technology uses disparate transparent polycrystalline ceramics and is sealed by laser.  The laser directly joins the disparate surfaces, protecting the electronic device from damage while ensuring a high-quality seal. This state-of-the-art technology provides  superior packaging for biomedical implant devices that has long-term biocompatibility. It also provides safe and leak-proof seals.
