Abstract
Living organisms exhibit integrated perception and reflexive motion, allowing instantaneous responses to environmental stimuli. Inspired by the mimosa plant, we present a self-powered triboelectric-photonic organic transistor memory (TPOTM) that couples mechano-optical sensing with adaptive logic within a single device. The memory behavior arises from a synergistic triboelectric-photonic mechanism, where light excitation induces charge trapping while triboelectric potentials dynamically modulate channel conductance through tactile interactions and mechanical impacts. This dual-stimulus coupling enables programmable optical writing and triboelectric erasing, realizing a mimosa-like, threshold-gated “sense-protect-recover” reflex at the device level. When integrated with photovoltaic modules, the TPOTM functions as a self-powered sensory-logic unit that autonomously triggers protective mechanisms against mechanical impacts. While the actuation is externally driven, the perception and decision-making processes operate entirely without external bias. This work presents a bio-inspired platform for self-powered, adaptive electronics, providing a pathway toward integrated sensing-response devices capable of real-time environmental adaptation.
