Abstract
An electrostatic sensing device comprises an electrostatic sensing module and a control unit electrically connected to the electrostatic sensing module. The electrostatic sensing module comprises a first electrostatic sensing element comprising opposite ends, and two first electrodes. The two first electrodes are separately located on and electrically connected to the two opposite ends of the first electrostatic sensing element. The first electrostatic sensing element is a single walled carbon nanotube or a few-walled carbon nanotube. The control unit electrically is configured to apply a direct voltage to the first electrostatic sensing element and measure a current/resistance of the first electrostatic sensing element.
