Abstract

The invention discloses an electronic skin for touch detection. The electronic skin comprises a flexible substrate, at least two conductive layers, and a plurality of electrodes. The conductive layers cover the two surfaces of the flexible substrate respectively; and the electrodes are arranged at the two ends of the conductive layers. The conductive layers include matrixes and first conducting particles dispersed in the matrixes. The electronic skin has characteristics of having stable output characteristic, having good consistency between individuals, being convenient to install, and enabling costs to be lowered.

Description

[0001] [technical field] [0002] The invention relates to sensors, in particular to an electronic skin for touch detection. [0003] [Background technique] [0004] Robots, as automation devices of artificial intelligence, are more and more integrated into the daily life of human beings, and perform related work instead of human beings in dangerous industries such as high temperature, high pressure, and explosive discharge. The current robot system has achieved many functions such as human vision, hearing and smell through the integration of various sensors. However, how to have a sensitive tactile function like humans has always been one of the challenging problems faced by robotic systems. For example, when the sweeping robot is moving, it needs to detect whether it touches the wall in time, and turn back to work, otherwise it will cause an endless loop. Now the sweeping robot adopts a more complicated structure, so that the collision triggers the light touch switch and is...
