Flexible Tunable-Plasticity Synaptic Transistors for Mimicking Dynamic Cognition and Reservoir Computing (Adv. Mater. 24/2025)

Abstract

Flexible Tunable-Plasticity Synaptic Transistors

A flexible synaptic transistor with tunable plasticity is developed using an IGZO channel and hybrid polyimide/Al₂O₃ dielectric. It achieves reversible switching from short-term to long-term plasticity via stimulus amplitude, enabling 94.1% neural-network accuracy and 4-bit reservoir computing. It paves the way for adaptive neuromorphic systems toward human wearable intelligence and robotic e-skin technologies. More details can be found in article number 2418418 by Min Zhang and co-workers.
