Benefits of technology

[0029]According to the present disclosure, the development of the tactile feedback device using electrostatic force is expected to

Problems solved by technology

In the case of electrical stimulation, it is difficult to deliver accurate tactile information due to a large difference from actual tactile information.
In the case of mechanical stimulation, practical application is difficult due to the complexity of components of the mechanical tactile device, large volume, high driving power, and the like, thereof.
However, existing actuators have a number of technical limitations.

Abstract

There is provided a tactile feedback device comprising: an array of surface charge generation units; and an array of pressure-generation units, wherein the array of the pressure-generation units is spaced apart from the array of the surface charge generation units, wherein the array of the pressure-generation units is movable relative to the array of the surface charge generation units, wherein an attractive or repulsive force is generated between a corresponding surface charge generation unit of the array of surface charge generation units and a corresponding pressure-generation unit of the array of the pressure-generation units, based on a polarity of surface charges induced in the corresponding surface charge generation unit.
