Figure 11. (A) The multimodal sensing characterization and mechanism of the spider web-like flexible tactile sensor^[195]; (B) the structure, multimodal sensing properties (temperature, humidity, plane strain, ultraviolet, magnetism, etc.), and preparation process of a highly flexible and stretchable matrix network e-skin^[196]; (C) composition of the skin-inspired piezoelectric tactile sensor array system and comparison with human skin^[197]. PDMS: Polydimethylsiloxane; SET: stretchable electrode; PI: polyimide; PVA: polyvinyl alcohol; PVDF: polyvinylidene fluoride; ADC: analogue-to-digital converter.
