Abstract :
Over the past few years, an eight-channel cochlear implant has been designed and tested by our group. The stimulator electronics are built around a custom low-power 4 μm CMOS gate array integrated circuit. The resulting chip is mounted on a suitable thick-film hybrid circuit together with a few discrete components, capacitors and resistors, used to interface the microprocessor and to provide its input data and power. The system is then housed in a hermetically sealed titanium case to ensure its long-term biocompatibility and implantation. The resulting system that is described here constitutes a very flexible and reliable device. Preliminary results are also summarized at the end
