Abstract: Disclosed is a virtual tactile implementation device, which includes one or more micro-displacement stimulation elements in close contact with a skin, a signal processor that applies a displacement signal to the micro-displacement stimulation element, and a power supply device that supplies electrical energy to the micro-displacement stimulation element and the signal processor, and the signal processor controls a waveform and an amplitude of the displacement signal to allow the micro-displacement stimulation element to selectively fire action potentials of a plurality of tactile receptors within the skin, and controls a time interval at which each of the action potentials is fired to allow the micro-displacement stimulation element to provide a sense of pressure or a sense of texture.
