Neural Engineering

 

For people with visual-, physiological impairments or neuro-degenerative disorders, biomedical implants hold some promises for an improvement in their future quality of life. Our contribution is the design of integrated circuits (ASICs), establishing a bidirectional connection between the brain and the external world. Within the BMBF-project “Kalomed” we developed the prototype of an implantable neural measurement system. A very challenging part in the design of such a system is the biological restriction which demands for an efficient and wireless energy and data transmission.
A new idea to deal with these restrictions is the data compression according to the theory of Compressed Sensing . Our approach is to already apply Compressed Sensing in the acquisition stage prior to the ADC.
Other research projects at our institute deal with new system and processor- architectures for neural measurement systems with stimulation features and optical transmission technologies in systems with several hundreds of electrodes
