Abstract

We have developed an implantable stimulation unit for multichannel functional electrical stimulation (FES) system applied to the restoration of motor functions. The stimulation unit implanted in the body is externally controlled and powered by an encoded carrier radio frequency of 1 MHz and a continuous frequency of 100 kHz, respectively. A new type of RF coil utilizing amorphous magnetic fibers was introduced to realize highly efficient of power transmission. Up to 16 independently controlled stimulus output channels are provided, with output channel selection, stimulus pulse amplitude and stimulus pulse rate controlled externally by the packet transmission method. A constant voltage stimulus pulse is generated with the D/A converter in the circuit of the implanted unit.
