What do flexible sensors need to learn?

What you want to ask is the flexible pressure sensor. Flexible pressure sensor needs to learn precision mechanical design, microcircuit foundation, analog electronic technology, digital electronic technology, single chip microcomputer principle and so on. According to the patent summary of Baidu Library on the application and development of flexible pressure sensors, the types of flexible pressure sensors are mainly divided into four directions: capacitive, piezoresistive, piezoelectric and frictional power generation. The working principle is relatively simple, but it is particularly difficult to design a novel and improved structure. With the continuous development of computer technology, intelligent control technology, sensing technology and artificial intelligence, flexible pressure sensor, as an important bridge of human-computer interaction, requires higher and higher pressure detection range and sensitivity. The flexible pressure sensor comprises an insulating shell, a microchannel flexible wire layer and a pressure sensitive layer. The micro-channel flexible cord layer is arranged in the insulating shell, and the center of the micro-channel flexible cord layer is not provided with a "back" type flow channel, and the "back" type flow channel is filled with corrugated metal. The pressure sensor is located between two groups of micro-head flexible wire layers, and concave grids are arranged corresponding to the positions of two groups of "back" flexible microchannel flexible conduits, and the grooves are filled with flexible pressure materials. Flexible pressure sensor involves many aspects and needs to learn a lot of knowledge.
