Presentation transcript:

Schematic signal pathway. Schematic signal pathway. To perform a specific motion of the prosthetic arm, the patient is thinking of this movement (1). This creates an impulse along the responsible nerve (2) and leads to a contraction of a specific muscle belly (3). The produced EMG signal is then recorded, rectified, and integrated within the IMES sensor (4). Via telemetry using a magnetic coil around the stump, these signals are transferred to the control unit, and forward telemetry is used to transmit power and configuration settings to the sensors (5). Within the belt-worn control unit, the preprocessed rectified EMG data (6) of the IMES are sent to the prosthesis (7), and the desired movement of the prosthetic device is performed (8). S.
