a The schematic diagram for the pain perception mechanisms of the creature. b The optical image of the memristor-based artificial synapse, in which s-SWCNTs and PEO: LiClO4 are used as the bottom-layer and top-layer materials, respectively. The protons and Li+ mimic the functions of Na+ and K+ in biological systems. c The AFM image with the length of the scale bar being 1 μm and d the XPS spectra of s-SWCNTs. The IV characteristics of the artificial synapses with the different sweeping voltages shown in d–f The enlarged IV characteristics in the voltage between 0 V and −1.5 V.
