a Schematic of artificial pupillary light reflex (left panel) and signal flow (right panel). b Circuit diagram of artificial pupillary light reflex. c Schematic of electrochemical reactions in the EC device. d CIELab color coordinates (L*, a*, b*) of the EC device during coloration. e Transient transmittance of the EC device at 520 nm. f Plot of PEC/P0 versus current, showing the light intensity modulation capability of the EC device. Error bars represent standard deviation (n = 4) g Light modulation properties under the application of light input and VInh, resulting in PSC modulation.
