Prosthetic hand control based on the acquisitionudand processing of surface electromyography signals (sEMG) is audwell-established method that makes use of the electric potentialsudevoked by the physiological contraction processes of one or moreudmuscles. Furthermore intelligent mobile medical devices are onudthe brink of introducing safe and highly sophisticated systems toudhelp a broad patient community to regain a considerable amountudof life quality. The major challenges which are inherent in suchudintegrated system’s design are mainly to be found in obtaining audcompact system with a long mobile autonomy, capable ofuddelivering the required signal requirements for EMG basedudprosthetic control with up to 32 simultaneous acquisitionudchannels and – with an eye on a possible future exploitation as audmedical device – a proper perspective on a low priced system.udTherefore, according to these requirements we present a wireless,udmobile platform for acquisition and communication of sEMGudsignals embedded into a complete mobile control systemudstructure. This environment further includes a portable deviceudsuch as a laptop providing the necessary computational powerudfor the control and a commercially available robotic handprosthesis.udMeans of communication among those devices areudbased on the Bluetooth standard. We show, that the developedudlow cost mobile device can be used for proper prosthesis controludand that the device can rely on a continuous operation for theudusual daily life usage of a patient.
