Method for preparing skin of robot with high flexibility

Abstract

The invention discloses a method for preparing skin of a robot with high flexibility. The method comprises the following steps of S1, utilizing plasma equipment for etching a thermosplastic elastomermatrix material to prepare a flexible elastic matrix, wherein the repetitive unit of the flexible elastic matrix is 1-100 microns, through micro / nano processing technologies of photoetching, microfluid control and 3D printing, particles are introduced to the surface of the repetitive unit, and micro / nano patterning of the surface of a prepared flexible substrate is achieved; S2, coating the surface of the micro / nano patterned flexible substrate with a graphene or carbon nano tube solution to serve as a conductive layer; S3, coating a sensor electronic chip element with a layer of coupling agent, and implanting a pressure sensor electronic chip original element which is subjected to surface treatment into the thermosplastic elastomer matrix through an embedding method. According to the method, electronic chips can be effectively combined with the matrix material, the efficiency of the chips is achieved, and the application range of the electronic skin is expanded.

Description

technical field [0001] The invention relates to the field of bionic robot manufacturing, in particular to a method for preparing flexible and high-strength robot skin. Background technique [0002] With the continuous integration of informatization and industrialization, the intelligent industry represented by robot technology is booming. People look forward to the development of humanoid bionic robots that are closer to humans and other organisms in the future. The sense of touch is a necessary medium for robots to directly interact with the environment. The sense of touch itself has a strong sensitivity and can directly measure various properties of objects and environments. Tactile skin is a new type of wearable, flexible and bionic tactile electronic skin, which can endow robots with the same sense of touch as humans and animals, making them more intelligent and humane. In order to cover complex three-dimensional surfaces and moving joints such as robots, tactile skin ...

Problems solved by technology

[0003] At present, some research groups in Japan and the United States have reported electronic skins based on organic field effect transistors, capacitive and piezoresistive, but each has advantages and disadvantages. For example, the use of rigid silicon-based materials makes the device non-transparent and non-transparent. Flexibility, the problem that the electronic chip and the base material cannot be effectively combined, which hinders the performance of the chip and greatly limits the application range of the electronic skin
