Abstract

Organic retinomorphic sensors are particularly effective for motion detection, offering the advantage of in-sensor processing that can remove repetitive static backgrounds. In this study, we investigate the important impact of high-k dielectrics in promoting charge accumulation to increase the intrinsic photo-response of photo-sensitive capacitors within this promising framework. We demonstrate a retinomorphic sensor array to detect the motion of a sample moving at different speeds and directions. These proof-of-concept results represent a promising advance toward scalable integration of organic retinomorphic arrays to meet the growing demand for more efficient motion tracking systems.
