Novel concept for a wireless and batteryless brain implant array

In case of a neuro-degenerative disorder, closed-loop brain stimulation is able to reduce tremor, rigidity, bradykinesia, as well as postural instability and consequently to improve the patient´s quality of life. Therefore, we investigate a human machine interface based on a multi-implant approach, which avoids drawbacks of conventional systems. The following paper presents concept, theory, as well as an initial prototype of a novel wireless power distribution / communication system together with the used signal processing. Finally, the publication shows a prospect to the future implant.
