US Patent 10331211 Device and method for providing tactile sensation

A device and a method for providing tactile sensation by using electrostatic force between an electrode and a user. The device for providing tactile sensation includes a plurality of electrodes arranged on a substrate, and a dielectric substance layer formed on the substrate and the electrodes, wherein the electrodes electrify the dielectric substance layer with an electric charge according to a driving voltage, so as to generate electrostatic force that provides tactile stimuli to a user who comes into contact with the dielectric substance layer.
