Abstract

Inspired by biological mechanoreceptors, we present a flexible artificial mechanoreceptor (FAM) based on high-performance VO₂ insulator-metal transition (IMT) memristor with the functions of sensing, spikes coding and information fusion for the anthropomorphic neurorobotics. The flexible VO₂ IMT memristors with the structure of Ti/Pt/VO₂/Pt via-hole show bi-directional threshold switching performance, good endurance (>2 ×10⁹) and excellent flexibility (>10³ bending cycles). The FAM comprised of three receptors (flexible pressure sensors) and one flexible VO₂ IMT memristor is able to detect, code and fuse the pressure information from different receptors into spike trains similar to the biological SA-Ⅰ mechanoreceptors, laying the foundation for the flexible electronic skin of anthropomorphic neurorobotics in the future.
