In order to realize the modular design of electronic bionic skin, a thin-film temperature-sensitive sensor based on graphene nanosheets was designed. At the same time, the capacitive silver-silicon / silicone rubber composite was used as the elastic dielectric and the silicone conductive silver paste as the flexible upper electrode. Sensor based on which a polyimide flexible substrate is proposed and an all-flexible temperature / pressure tactile sensor which can be used as a bionic skin of an intelligent robot is proposed and designed into a modular array structure with splicing characteristics. The structure design, detection mechanism and signal acquisition and processing system of the temperature / pressure tactile sensor can be realized by the combination of temperature, pressure and temperature / pressure sensing experiments. The flexible temperature / pressure tactile sensing array and signal extraction system can realize the tactile perception Function, provides a design solution for the study of wearable artificial skin.
