Outline of Final Research Achievements

In this study, a distributed multiple image sensor device was developed. The control signals for the image sensor are generated in the chip. And, a chip control signal is transmitted on the power line. Thus, the number of the input lines is reduced to two. We built a multiple sensor system that sensors were driven sequentially with only two lines.
As a way to reduce the number of lines, an implantable device based on intra-body communication technique. By contacting an image sensor with output electrodes on a mouse brain, weak electrical current signal was transmitted to another electrode on the body.
