Haptic feedback button

초록

Provided is a haptic feedback button, which includes: a substrate; a lower electrode provided on an upper portion of the substrate, and formed by patterning a ground electrode and a touch sensing electrode; an upper electrode, provided above the lower electrode with an interval from the lower electrode, to which a driving voltage is applied; and a cover provided on an upper portion of the upper electrode, wherein a piezoelectric polymer is provided on an upper portion of the lower electrode or a lower portion of the upper electrode so that fretting vibration may be generated when the piezoelectric polymer is in close contact with the lower electrode or the upper electrode that are disposed to face each other.
