摘要：
This paper reports a fully batch-fabricated cochlear array with a current-driving ASIC. The array includes a stiffness-controlling ringed-channel for stylet wire placement and a self-curling parylene substrate capable of precurving the array to a 0.5 mm radius of curvature. A 32-site array with IrO sites on 250 mu m centers is realized along with a four-channel stimulation ASIC capable of driving multipolar site configurations with biphasic pulses of up to 500 mu A/channel.
