What can replace a finger to touch a screen?
Capacitive touch screen is the use of human body current sensing work. It is a composite glass screen of four layers. The inner surface of the glass screen and the interlayer are coated with a layer of ITO (coating conductive glass), and the outer layer is a thin layer of silica glass protective layer.
In the induction of the capacitive screen, as long as there is a weak current can be induced by the screen, so with conductive and micro current things can control the capacitive screen.
The touch screen is basically a capacitive screen that uses a capacitor pen instead of the finger to touch the screen directly.
