Problems solved by technology

When the array type tactile sensor is used in a large area, there are many leads, and the conditioning circuit is more complicated. In addition, if the electrode width is increased during the production process, the effective capacitance can be increased, and the generated noise capacitance will also be increased at the same time, which cannot effectively solve the problem. Contradictions Between Capacitance and Noise Capacitance

[0004] The patent application number 201621268241.5 discloses a capacitive tactile sensor with a patterned microstructure array. The pressure sensor is designed with a microstructure pattern, and the processing and preparation methods are complicated. The capacitance has a great influence, and the array capacitance produces more electrode leads, which requires high processing technology and is not easy to process on a large scale
