摘要
Abstract Close imitation of synaptic metaplasticity is an important objective in the neuromorphic domain. Progress has been made in solid‐state electronics with high‐voltage dynamics, which, nevertheless, marks a significant inconsistency with the biological systems in aqueous media. Here, the concept of reticular photoelectrochemical transistor (RPECT) is proposed and devised that can realize metaplasticity with biochemical modulation. Based on the ambipolar behavior of a metal–organic framework channel gated by a photosensitive hydrogen‐bonded organic framework electrode, biochemically modulated positive/negative photoconductivity and metaplasticity with the typical features, e.g., the nonmonotonic enhanced depression effect region and the threshold sliding are achieved. Taking advantage of such unique properties, in‐sensor preprocessing and in‐memory computing are further implemented for efficient image recognition. This work realizes the aqueous metaplasticity by a new device of RPECT, which also introduces the biochemical modulation into image recognition, providing a perspective for future development of machine vision processing.
