A telemetry operated vestibular prosthesis

A telemetry operated vestibular prosthesis has been developed. The telemetry is designed to provide power to the implantable circuits and maintain bi-directional communication in a packet-based manner. It uses only one pair of inductively coupled coils. Preliminary measurements are shown, including in-vitro operation of the stimulation and recording functions. For a 10 MHz carrier frequency and a 7 mm distance between the coils, the downlink and uplink data streams operate at 400 kbps and 600 kbps, respectively.
