Abstract Various forms of intelligent light‐controlled soft actuators and robots rely on advanced material architectures bionic systems to enable programmable remote actuation multifunctionality. Despite advancements, significant challenges remain in developing that can effectively mimic the low‐intensity, wide‐wavelength light signal sensing processing functions observed living organisms. Herein, we report a design strategy integrates light‐responsive artificial synapses (AS) with liquid crystal networks (LCNs) create LCN (AS‐LCNs). Remarkably, AS‐LCNs be controlled intensities as low 0.68 mW cm −2 , value comparable intensity perceivable by human eye. These perform sensing, learning, memory within wide wavelength range from 365 nm 808 nm. Additionally, our system demonstrates time‐related proofs concept for tachycardia alarm porcupine defense behavior simulation. Overall, this work addresses limitations traditional reception processing, paving way development emulate cognitive abilities image

Reconfigurable graded adaptive asymmetry-Schottky-barrier phototransistor for artificial visual system with zJ-energy record

Applied Physics Reviews, Journal Year: 2025, Volume and Issue: 12(2)

Published: May 23, 2025

Visual perception, memory, and adaptation processes are critical functions in biological systems that enhance responsiveness, improve survival fitness, reduce information redundancy complex environments. Therefore, the development of adaptive bionic vision with high efficiency, low complexity, minimal energy consumption has become a key objective. However, most devices suffer from either structures or non-reconfigurable functionalities, hindering further application for systems. Here, first time, an asymmetry-Schottky-barrier MoS2 phototransistor is demonstrated reconfigurable visual system selective memory graded functions. More importantly, device exhibits new record ultra-low ∼90 zJ per synaptic event. Several important behaviors, such as sensitivity, desensitization, accuracy, self-recovery, successfully realized adjusted by asymmetry-Schottky-barriers. These results pave way toward efficient, low-energy, applications machine vision, robotics, human-machine interfaces.
