Problems solved by technology

[0006] In view of the shortcomings of traditional silicon-based, photoelectric, and piezoelectric 3D force tactile sensors that are not flexible and easy to conform, and the 3D force tactile sensor with the same surface electrode structure is prone to detachment of the pressure-sensitive material from the electrode under force, affecting the stability of the sensor In order to solve the problems of low sensitivity and low sensitivity, researchers at home and abroad have carried out extensive research on flexible three-dimensional force tactile sensors. How to improve the sensitivity of three-dimensional force tactile sensors has become one of the research hotspots.

Abstract

The invention discloses a three-dimensional force flexible touch sensor based on a conductive sensor. The three-dimensional force flexible touch sensor based on the conductive fabric is characterizedin that: 4N flexible touch sensitive units which consist of tensile sensitive conductive fabrics are arranged at equal intervals on an inner wall of a semispherical cavity in spatial three-dimensionalarrangement so as to construct a differential type three-dimensional force flexible touch sensor. The three-dimensional force flexible touch sensor based on the conductive fabric provides a feasibledesign scheme for electronic skin to realize high sensitivity three-dimensional force touch sensing.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a three-dimensional force flexible touch sensor based on conductive fabric. [0002] technical background [0003] Electronic skin (e-skin), as an artificial flexible electronic device with high flexibility and stretchability, which can realize the external environment information perception function like human skin, has become a research hotspot in the fields of intelligent robots and human-computer interaction. The three-dimensional force tactile sensor can simultaneously measure force or moment components in more than two directions, and is one of the most important sensors for intelligent robots. With the development of flexible bionic tactile sensors and the advancement of intelligent robot technology, higher requirements have been put forward for tactile sensors, requiring them to not only have the ability of human tactile perception, but also accurately obtain three-dimensional force...
