Fig. 2From: Floating EMG sensors and stimulators wirelessly powered and operated by volume conduction for networked neuroprostheticsSchematic representation of the floating semi-implantable devices used for acute implantation, and a low-level control unit of the external system. The semi-implantable devices include injectable intramuscular electrodes and a miniature electronic circuit adhered to the skin. The low-level unit of the external system delivers HF current bursts for powering, EMG sensing and electrical stimulationBack to article page
