Flexible implantable microelectrodes for rehabilitation

Introduction: Electrodes are used as technical-biological interface for electrostimulation and signal recording. Depending on the field of application and the required selectivity, different electrode structures are employed. For each application, it has to be individually decided which degree of invasiveness is tolerable in order that the required selectivity can be achieved. Materials and Methods: By means of microtechnology, is it possible to use photolithography to fabricate very small, implantable electrode structures of arbitrary geometry and almost unlimited number of electrode sites. As backbone material…
