受视网膜细胞对光的反应方式的启发，视网膜形态传感器有望实现对移动物体的快速识别。与传统的光学传感器不同，这些传感器被设计成响应于照明的变化而不是在恒定照明下产生信号。这份报告是第一次演示的视网膜形态传感器采用有机半导体作为吸收剂。该传感器在恒定的测量条件下表现出稳定性，最长可达1小时，并且通过选择外部电阻器可以调节特性衰减时间，表现出低至10 μ s，比以前的设备快约10000倍。
Inspired by the way retinal cells respond to light, retinomorphic sensors are hoped to enable rapid identification of moving objects. Unlike conventional optical sensors, these sensors are designed to produce a signal in response to changes in illumination but not under constant illumination. This report represents the first demonstration of a retinomorphic sensor employing organic semiconductors as the absorber. The sensor exhibits stability under constant measurement conditions up to a period of 1 h and characteristic decay times that are tunable through a choice of external resistor, demonstrated down to 10 mu s, roughly 10 000 times faster than previous devices.
