Multi‐Level Non‐Volatile Bipolar Optoelectronic Transistor for Dynamic Perception and Recognition

ABSTRACT

The emerging intelligent driving systems (IDS) have created a critical need for hardware capable of efficient dynamic vision perception and processing. The current machine vision implementations, which operate on fragmented sensing, memory, and computing architectures, incur high energy consumption and latency from frequent data transmission. Here, we report a reconfigurable 2D heterostructure‐based intelligent optoelectronic device that can simultaneously sense, store, and process visual information. Due to the light‐modulated stored charges and their non‐volatile nature in the top‐floating‐gated configuration, the heterostructure device shows symmetric positive and negative photoresponse, enabling the detection of moving objects via inter‐frame differencing. Moreover, the progressive photoresponse ensures over 8‐bit distinct storage states, which can be directly mapped into convolutional neural networks for achieving high‐accuracy motion pattern recognition. The multifunctional integration of 2D devices offers a feasible approach to constructing compact and efficient IDS hardware.
