The working principle and advantages and disadvantages of

To learn about a capacitive transducer, it is important to know the basics of a parallel plate capacitor. Being the simplest form of a capacitor, it has two parallel conducting plates that are separated to each other by a dielectric or insulator with a permittivity of Ε (for air).

capacitance Principle of mutual capacitive touch screen

In the analysis of capacitive touch screen principle, we first come to understand the working principle of resistive touch screen. Resistive touch screen is mainly used to control the pressure sensor. It is composed of a display screen and a close contact with the display of the resistance film screen. The resistive film screen is usually divided into two layers, one layer is made of glass or
