Abstract

The invention discloses an all-flexible capacitive tactile sensor. The all-flexible capacitive tactile sensor is characterized in that a flexible substrate is arranged, wherein a shielding layer is arranged on the lower surface of the flexible substrate, and a flexible conductive lower polar plate and flexible conductive upper polar plate electrodes surrounding the flexible conductive lower polar plate at intervals are arranged on the upper surface of the flexible substrate; an inverse concave elastic dielectric layer is arranged between the flexible conductive lower polar plate and the flexible conductive upper polar plate electrodes in a covering manner, an inverse concave flexible conductive upper polar plate is arranged on the periphery of the elastic dielectric layer in a covering manner, and an inverse concave flexible protective layer is arranged on the periphery of the flexible conductive upper polar plate in a covering manner. All structures of the all-flexible capacitive tactile sensor disclosed by the invention are flexible, and upper and lower polar plate leads are led to the same flexible substrate, so that the problems that leads are fussy, unattractive and unlikely to maintain when an array structure is designed are solved.

Description

technical field

[0001] The invention belongs to the technical field of sensing, and relates to a fully flexible capacitive touch sensor for artificial intelligence skin. Background technique

[0002] The sense of touch is an effective way for intelligent robots to perceive external information, and the perception of tactile information is an essential link in the field of robot sensing technology. A complete tactile information is an organic fusion of information such as force, hardness, temperature and humidity, and slippage. As a kind of bionic skin, the tactile sensor is widely used in the tactile perception system of intelligent robots, which provides a reliable guarantee for intelligent robots to complete predetermined functions in complex and diverse environments. There are many kinds of commonly used robot tactile sensors, which are mainly divided into resistive, capacitive, photoelectric, piezoelectric and inductive according to different sensitive mechanisms.
