Embodiment

[0028] Such as Figure 1 to Figure 3 As shown, a new sensing system structure of human biomimetic electronic skin, which includes positioning layer gel based on acrylamide and lithium chloride and BMIMBF based on ionic liquid 4 Polymer sensing layer gel; the acrylamide and lithium chloride-based positioning layer gel and the ionic liquid-based BMIMBF 4 VHB bands are arranged between the gels of the polymer sensing layer.

[0029] The positioning layer based on acrylamide and lithium chloride is composed of a single-layer ion gel, and the single-layer ion gel is made of acrylamide and lithium chloride as a conductive glue.

[0030] Among them, the acrylamide used to prepare the sensory layer is usually a colorless transparent flaky crystal, and its molecular formula is C 3 h 5 NO, the molecular weight is 71.08, the pure product is a white crystalline solid, easily soluble in water and methanol, slightly soluble in chloroform and ethyl acetate, slightly soluble in benzene, a...

Abstract

The invention relates to a novel perception system structure for human bionic electronic skins. The structure includes acrylamide and lithium chloride based positioning layer gel and ionic liquid BMIMBF4 polymer based perception layer gel; and a VHB belt is arranged between the acrylamide and lithium chloride based positioning layer gel and the ionic liquid BMIMBF4 polymer based perception layer gel. Thus, the contradiction between positioning precision and system complexity in a distributed sensing system can be solved; and the structure can enhance the positioning precision without increasing the complexity of the system, so that the low cost and reliability of the system can be guaranteed.

Description

technical field [0001] The invention relates to the field of design and manufacture of a bionic electronic skin, in particular to a novel perception system structure of a bionic electronic skin for a human body. Background technique [0002] With the continuous integration of industrialization, intelligence, and informatization, industrial informatization represented by robot technology is developing rapidly, and tactile perception is applied to grasping control, state judgment, and pattern recognition on robots more and more widely. This requires it to have the same perception ability as human beings, and can instantly judge the aspects required by the tactile perception system such as the nature of the grasped object and material characteristics. Among them, the electronic skin sensing system, as an important flexible sensing system, is related to the multi-functionalization, informatization and industrialization of next-generation robots, intelligent hardware and other eq...
