electrode arrays provide a reliable interface for permanent brain recordings. Being very soft and flexible, they allow for easy implantation and gently fit to the curvature of the brain.

A biocompatible ceramic encapsulation hermetically encloses an implanted electronics unit that preprocesses the data. A key component of this system is a custom-made microchip (ASIC) developed in cooperation with the Institute of Microelectronics at the University of Ulm (Prof. Maurits Ortmanns). It amplifies neuronal signals in many independent channels (currently 32) and digitizes them at high sampling rate (currently 1 kHz) while, at the same time, allowing for swift and flexible switching between recording and stimulation mode.

Thanks to an inductive power supply via an external unit, it also works without a battery. This eliminates the need for surgical replacement when battery power decreases (as is still the case in many of today’s implantable systems). Via the same external unit, brain signals are transmitted wirelessly to a Computer Unit for processing.

CorTec is also providing support, services and components of the Brian Interchange System such as AirRay Electrodes, encapsulation technology, overmolding technology and device assemply to Medtech Companies and start up in the field of neurotechnology.
