We report on an optical telemetric link capable of providing a high data rate at a low power consumption for the transcutaneous transmission of neural signals. The telemetric link is designed for operation as the interface between an implanted cortical array and an external receiver. By converting the digitized neural signals to a stream of infrared optical pulses, the optical telemetry wirelessly...
This paper presents the system level model of a transcutaneous optical telemetric link (TOTL) system for neural recording. Varieties of noise sources are characterized. Power distribution is described by means of Gaussian model approximation. Strategies for designing of the optical receiver that maximize signal to noise ratio (SNR) are discussed. The system level model presented here allows designers...
