What can replace a finger to touch a screen?
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.
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.
The touch screen is basically a capacitive screen that uses a capacitor pen instead of the finger to touch the screen directly.
