Research Abstract

Computer simulation was executed to examine the realizability of signal transmission between electric devices and human nervous systems using implanted coil. A toroidal coil surrounding a nerve worked as a neuroreceptor junction, which transmits electric current pulse to all or a part of the nerve fibers in the nerve. It was assured that a toroidal coil has a potential to transmit electric signals minimally invasively in comparison to direct junctions.
