Phone holder pen, with a slot on the top to support cell phones (mobile phones) 

Bring the pen with you and have a phone support everywhere;

Put your mobile phone into the slot, relax and lean back and enjoy watching your phone

The principle of capacitive touch is that when a finger or other conductive material touches the panel, the panel will detect the change in the capacitance of the surface and generate an electronic signal to determine the touch position. Therefore, you can use your fingers or other conductive materials to control; and the traditional non-conductive materials such as plastic resistive stylus cannot be controlled. Before, some netizens demonstrated using sausages or other foods to manipulate the iPhone; some netizens made their own iPhone stylus, and placed a piece of conductive cotton in front of the general pen tip to control the iPhone. The capacitive stylus currently on the market mainly uses conductive materials such as conductive cotton, rubber (the surface is coated with conductive paint), and conductive fibers. The principle is to use conductive materials on the surface.
