A Bioinspired Retinomorphic Device for Spontaneous Chromatic Adaptation (Adv. Mater. 51/2022)

Retinomorphic Devices In article number 2206816, Yinlong Tan, Tian Jiang, and co-workers report a retinomorphic sensor based on wavelength-dependent bipolar photoconductivity induced by the photocontrolled adsorption and desorption of oxygen molecules on the surface of platinum diselenide. The antagonistic receptive field of the human retina is successfully mimicked, and spontaneous chromatic adaptation based on this device provides a basis for developing all-in-one vision perception hardware with simplified circuitry.
