Technical Details for Proteon™ by SCHOTT Primoceler Oy

Miniaturization, enhanced functionality, and performance are critical for active medical implants and are becoming standard requirements for electronic components. Proteon™ glass packaging by SCHOTT Primoceler Oy is opening new doors towards miniaturization and design possibilities for future implant solutions.

A new breed of ultra-miniaturized and reliable hermetic sealing

Gas-tight sealing

Proteon™ by SCHOTT Primoceler Oy creates a fully hermetic seal, offering complete protection for sensitive encapsulated electronics in active medical implants.

Ultra-miniaturization

The latest technological developments offered by SCHOTT Primoceler Oy enable implant size dimensions starting from smaller than 1 millimeter.

RF transparency

Transparent glass encapsulation eliminates the need for wired connections as radio frequencies (RFs) can travel through the Proteon™ all-glass package from SCHOTT Primoceler Oy. This reduces bulk and complexity in device designs while allowing devices to be internet-connected by emitting and receiving wireless data signals.

Flexible customization

SCHOTT Primoceler Oy R&D experts will work with you at every step – from concept to volume production – to overcome your development challenges and create a customized solution.
Specifications
