Abstract :
We have developed a CMOS image sensor with hexagonally shaped outline for wide-area brain functional imaging. The hexagonal shape of the sensor chip allows covering wide area on curved surface of the brain by placing multiple chips. In this paper, we report two results for wide-area brain functional imaging. First, we designed a hexagonally shaped CMOS-based imaging device which has highly sensitive pixels and evaluated the characteristics of the sensor. Second, we successfully demonstrated fluorescent imaging using the sensor.
