CMOS-Based Neural Interface Device for Optogenetics.

Optical and electronic neural interface devices based on CMOS technology are presented. Concept, design strategy, and fabrication of the CMOS-based optoelectronic neural interface devices are described. The devices are based on a technology of implantable CMOS image sensor. To realize addressable local optical stimulation, blue light-emitting diode array chip was integrated on the implantable CMOS image sensors. Functional demonstrations of the devices are also presented. Optical stimulation capability was demonstrated in both in vitro and in vivo experiments. Further perspective including wireless device architecture is also presented.
