1. An electrometer comprising:

  • a sensing module comprising an electrostatic sensing element comprising two opposite ends;

    a control module electrically connected to the two opposite ends;

    wherein the electrostatic sensing element is single walled carbon nanotube or few-walled carbon nanotube, the control module is configured to measure a resistance variation Δ

    R of the electrostatic sensing element and convert the resistance variation Δ

    R into a static electricity potential.
