Abstract

A transdermal communication apparatus and method is disclosed which utilizes a Hall Effect sensor to be implanted within a body and which acts to receive communication transmissions from an externally placed source. The sensor provides improvements relative to the ease of implantations, reliability, speed of processing, and communication integrity.
