Abstract

The invention provides a quick response pressure-sensitive thin film for an intelligent robot and a preparation method. A main material is a YBa2Cu3O7+delta / polyvinylidene fluoride composite material thin film. The process comprises the steps that firstly nano YBa2Cu3O7+delta and a polyvinylidene fluoride solution are uniformly mixed; then spinning is conducted; filament-shaped articles are smashed into fibroid powder; and finally flat laying, polarizing and hot pressing are conducted to obtain the pressure-sensitive thin film. The particle size of YBa2Cu3O7+delta powder bodies is 400-800 nm, and the weight ratio of the nano YBa2Cu3O7+delta powder bodies to polyvinylidene fluoride (PVDF) is 1:1-50. Within the application range of the pressure of 0.1-8 MPa, change of the resistance value has five orders of magnitude, and the quick response pressure-sensitive thin film can be widely applied to an intelligent robot sensor and has the corresponding performance of flexibility, quickness, sensitivity and precision.

Description

technical field [0001] The invention belongs to the field of sensors and materials, and in particular relates to a fast-response pressure-sensitive film for an intelligent robot and a preparation method thereof. Background technique [0002] With the improvement of the degree of intelligence, there are more and more applications of robot sensors. There are three main types of intelligent robots: interactive robots, sensing robots and autonomous robots. Starting from anthropomorphic functions, vision, force, and touch are the most important. They have already entered the practical stage, and hearing has also made great progress. Others include smell, taste, slip, etc., corresponding to a variety of sensors, so the robot sensing industry has also formed. production and research capabilities. [0003] Sensor (Sensor) is a common but very important device. It is a device or device that senses various quantities that are specified to be measured and converts them into useful si...
