Abstract

In this paper, an improved design of implantable SoC with monopolar biphasic constant current stimulation (CCS), double-electrode multiple stimulation, and the evoked compound action potential (ECAP) acquisition is proposed and fabricated for the bone-guided cochlear implant (BGCI) microsystem. Through the same pair of coils in 13.56 MHz, the implanted SoC is powered wirelessly and the stimulation patterns are sent from the external unit. Electrical measurement has been successfully performed. In vivo animal tests on guinea pigs have shown that the Wave III of electrically evoked auditory brainstem (EABR) response is successfully evoked by the stimulation of the improved BGCI microsystem.
