Abstract
A hover controlling device includes a sensing unit and a hover control unit. The sensing unit includes a plurality of first electrostatic sensing elements, a plurality of first electrodes, a plurality of second electrostatic sensing elements, and a plurality of third electrodes located on a substrate. Each first electrostatic sensing element and each second electrostatic sensing element include a single walled carbon nanotube or a few-walled carbon nanotube. The resistances of the plurality of first electrostatic sensing elements and the plurality of second electrostatic sensing elements are changed in process of a sensed object with electrostatic near, but does not touch the plurality of first electrostatic sensing elements and the plurality of second electrostatic sensing elements. The hover control unit is electrically connected to the plurality of first electrostatic sensing elements and the plurality of second electrostatic sensing elements.
