ABSTRACT:
An optical transdermal link. The interface consists of two modules. An internal module is placed just inside the skin, and an external module is placed just outside the skin and facing the internal module. The external module is connected to a host processor via high speed serial lines. The external module contains one or two laser diodes with drivers, and one photodetector with preamplifier. The internal module contains a photocell array to provide power for itself, a photo detector, preamplifier and a clock recovery circuit for detecting the incoming signal, and a laser diode and driver for the outgoing signal. The internal module also contains modulation/demodulation and neural interface circuits peculiar to the specific application.
