▎ 摘　　要

Neuromorphic perceptual system (NPS) is inspired by the interaction between organisms and environment, which has boosted many emerging fields like human-machine interfaces and bionic robots. Laser-induced graphene (LIG) can be a fast, low cost, and accurate patterning technology toward a flexible and biological plausible NPS. While, to unleash the full potential of LIG, thorny issues like low endurance and limited stretchability should be addressed. Herein, high-performance ultraviolet LIG (UV-LIG) based sensors and electrodes are introduced for building flexible artificial sensory neuron (ASN). The UV-LIG can be fabricated with a fine linewidth of approximate to 75 mu m and a high conductivity of 3900 +/- 150 S cm(-1), which facilitates the demonstration of LIG toolbox, containing bending sensors, flexible heaters, etc. The transferred LIG electrodes retain good conducting property (only approximate to 12.7% increment in resistance) and enable large stretchability (up to 150% strain), outperforming most of the LIG-based strain sensors. As a proof-of-concept, an artificial sensory neuron that is able to mimic the strain perception of somatosensory system is realized based on the integration of LIG-based functional components and an InGaZnO (Indium-Gallium-Zinc Oxide, IGZO)-based synaptic transistor. This work can provide an efficient patterning methodology as well as essential components for neuromorphic perceptual systems.
