Abstract
A retinomorphic sensor is demonstrated employing organic semiconductors. The sensor produces an output voltage in response to changes in illumination, but zero output voltage under constant illumination. The device is stable for periods up to one hour, exhibits a decay constant tunable through choice of external resistor, with fastest response times below 10 μs.
