Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Please refer to figure 1 , this embodiment discloses a piezoresistive electronic skin, which includes:

[0038] Two flexible substrates 11, 12;

[0039] Two conductive layers 21, 22 are respectively coated on two flexible substrates 11, 12, and the two conductive layers 21, 22 are in contact with each other;

[0040] The two conductive electrodes 31, 32 are in contact with the two conductive layers 21, 22 respectively.

[0041] The at least one flexible substrate is a polydimethylsiloxane film, at least one side of the polydimethylsiloxane film has a micro-nano pattern, and the size of the pattern is between 0.1-500 μm.

[0042] The conductive layers 21 and 22 include a carbon nanotube film, and the carbon nanotube film is mainly composed of a carbon nanotube interweaving network. The light transmittance of the carbon nanot...

Abstract

The invention provides piezoresistive electronic skin and a preparation method thereof. According to the piezoresistive electronic skin, carbon nano tube films are adopted to serve as conductive layers, polydimethylsiloxane, polyethylene terephthalate, polyvinyl alcohol, polyvinyl formal, polyethylene and other materials provided with micronano patterns serves as substrates, and therefore the substrate has the advantages of being high in flexibility, prone to bending and the like, is low in operating voltage, little in power, high in sensitivity, and short in response time. More importantly, the patterning flexible substrates are adopted to serve as a base body, and sensitivity of the electronic skin to external tiny applied force is greatly improved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a piezoresistive electronic skin and a preparation method thereof. Background technique [0002] 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. The birth of electronic skin will bring great changes to the robot system, so that the robot can obtain more information from the external environment. [0003] Although since 2004, some research groups in Japan and the United States have reported electronic skin bas...
