a Conventional sensory computing, and in-sensor computing systems. For conventional sensory systems, analog sensory data are initially converted to digital signals through an analog-to-digital converter (ADC), subsequently stored in memory temporarily, and finally sent from memory to the processing unit. While for in-sensor computing system, multiple connected sensors can directly process sensor information directly, thereby obviating the sensor/processor interface and integrating sensing and computing functions. b Schematic diagram of artificial retinal vision system containing L/M/S cones and retina-inspired 2D ferroelectric bulk photovoltaic effect.
