ABSTRACT:
This invention describes a method for a haptic (tactile) feedback to a user of an electronic device having a touch display (screen) by utilizing an electrostrictive polymer as a combined haptic-seal actuator attached to the touch screen. In addition, the combined seal-actuator also makes a shock absorber. The electrostrictive polymer is a suitable material for haptic-seal-shock absorbing actuator because of its robustness and large stroke.
