CorTec receives Science-Business Cooperation Award 2022

Represented by Martin Schuettler, CorTec received the Science-Business Cooperation Award for science and economy 2022 by the University of Ulm, Germany.

Three electrical engineers from the Institute of Microelectronics received a Science-Business Cooperation Award for the development of a 32-channel microchip that is used as the heart of a biomedical implant for neuromodulation. Institute director Professor Maurits Ortmanns, Dr. Joachim Becker and Stefan Reich are cooperating closely with CorTec, as part of a long-term BMBF project.

Neuromodulation systems can both record electrical signals from the brain and electrically stimulate nerve tissue in a targeted manner. Particularly promising is so-called “closed-loop” neuromodulation, in which the stimulation parameters are precisely matched to the previously measured bioparameters. Such brain-stimulating medical implants are already being used successfully in the treatment of various neurodegenerative diseases. Therapeutic successes have also been achieved in people suffering from chronic pain or depression. A first version of CorTec’s neuromodulation system is already in the FDA approval process for human application.
