APPARATUS AND METHOD TO REALIZE DYNAMIC HAPTIC FEEDBACK ON A SURFACE

A haptic device including a first electrode including a first sub-electrode configured to receive a first voltage, and a second sub-electrode configured to receive a second voltage, a second electrode overlapping with the first electrode, and a deformable layer located between the first and second electrodes and configured to deform in response to the applied first and second voltages, and to change a relative position of at least one of the first and second sub-electrodes with respect to the second electrode, wherein the first and second voltages are in reference to the second electrode.
