Signal evaluation of capacitive EMG for upper limb prostheses control using an ultra-low-power microcontroller

Upper limb myoelectric prostheses drives are controlled by muscle signal, generated by electrochemical effects in the tissue. State of the art electrodes use the conductive measurement principle for acquiring the signal to control these active prostheses. Some problems, resulting from the necessary conductive skin contact, are associated with the state of the art electrodes. For this reason, a capacitive electromyography (EMG) prototype,...
