Abstract :
A new cochlear implant system for animal experiments is proposed. The system uses a DSP-based sound processor to implement the six-channel continuous interleaved sampling (CIS) speech processing strategy. An infra-red telemetry is designed to remotely connect the power-demanding sound processor to receiver/stimulator attached on the animal. This enables the animal to move freely. The receiver/stimulator consumes about 40 mW, thus can operates for about 200 hours without changing battery
