Ultrasensitive Pa‐Level Persistent Mechanoluminescent Material Toward All‐Optical Neural Synapses for Tactile‐Visual Information Recognition and Memory

, a micron-scale imaging resolution (≈200 µm), and a 36-hour memory capacity. These properties enable thermal-activated information awakening and visual imaging over 1000 cycles, with a memory accuracy 209% superior to the Ebbinghaus curve. This work not only advances the design of all-optical synapses but also forges a pivotal connection between ML and neuromorphic engineering, propelling energy-efficient, light-driven artificial intelligence.
