Ultralow‐Power Machine Vision with Self‐Powered Sensor Reservoir (Adv. Sci. 15/2022)

Ultralow‐Power Machine Vision In article number 2106092, Bobo Tian, Hui Peng, Chungang Duan, and co‐workers demonstrate that photovoltaic sensors can be used for in‐sensor reservoir computing (RC). Brain‐inspired vision is achieved by in‐sensor RC based on self‐powered Cs2AgBiBr6 photontic devices. Both image processing and dynamic video analysis are energy‐efficiently achieved with a high accuracy of 99.67% for face classification and 100% for dynamic vehicle flow recognition.
