Electronic skin of friction electrostatic induction type

Abstract

The invention provides an electronic skin of a friction electrostatic induction type, and the electronic skin comprises a friction layer, an upper electrode, an insulating layer, a lower electrode and a flexible substrate, wherein the friction layer, the upper electrode, the insulating layer, the lower electrode and the flexible substrate are sequentially arranged in a fixed manner from the top to the bottom, and the upper and lower electrodes are insulated from each other. Each intersection point of the upper and lower electrodes represents one detection position. When human skin touches any detection position, the corresponding electrodes of the upper and lower electrodes respectively output a signal, so the touch position can be obtained. The electronic skin employs the friction electrostatic induction effect, and generates an electric signal through the contact and separation of a human body with the friction layer, so as to sense the touch condition of an external object. The electronic skin has a self-drive function, is good in stability, is high in sensitivity, and is quick in response. Meanwhile, the electronic skin employs a flexible polymer thin film material with the biocompatibility, and is wide in application range.

Description

technical field [0001] The invention belongs to the field of sensors, and in particular relates to a frictional static induction electronic skin. Background technique [0002] In recent years, scientists have been working hard to realize technology that enables electronic products to gain the ability of human touch. Electronic skin is a system that allows robots to have a sense of touch. It has a simple structure and can be processed into various shapes. It can be attached to the surface of the device like clothes, allowing the robot to perceive information such as the location and orientation of objects. To simulate, restore or even replace human skin, electronic skin must first have a sense of touch, that is, the most basic function of sensing different external pressures and smoothly transmitting tactile signals just like human skin. In 2003, the research team of the University of Tokyo in Japan made a thin film of pentacene molecules, a low-molecular organic substance, ...

AI Technical Summary

Problems solved by technology

[0003] The main problem in the existing technology is: the current electronic skin needs battery or external power supply for monitoring, resulting in a waste of energy, thus bringing huge costs

Moreover, the regular replacement of the battery and the pollution of the battery itself limit its application fields.
