Raising control possibilities of myoelectric prostheses--The control of hand prostheses is based on the surface scan of myoelectric voltage caused by muscle contractions in an amputees arm stump. So far available prostheses only perform up to two different grip types. This paper introduces a control scheme that is able to execute a variety of grip types dependent on the patient's control signals. Therefore a platform is presented to adapt control parameters especially to the patients anatomy. Developed algorithms are flashed on a microcontroller, processing data online and controlling a new generation of prostheses (FZK-prosthesis, Forschungszentrum Karlsruhe).
