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 μs, roughly 10 000 times faster than previous devices.
