Abstract
The present invention provides a tactual sensor using a micro liquid metal droplet simultaneously having high sensitivity and good spatial resolution. A tactual sensor using a micro liquid metal droplet according to an exemplary embodiment of the present invention includes: a first film having a first electrode layer; a second film having a second electrode layer facing toward the first electrode layer; an insulating layer provided on the second film while covering the second electrode layer; and a main body disposed between the first electrode layer and the insulating layer to form a chamber corresponding to the first electrode layer and the second electrode layer and accommodating a micro liquid metal droplet in the chamber.
