Abstract:
A haptic actuator is presented. The haptic actuator has an electropermanent magnet having a deactivated state and an activated state for a net magnetic field thereof. A layer of ferromagnetic material or magneto-active polymer is located opposite an end of the electropermanent magnet, and is configured to generate a haptic effect by being actuated toward the end of the electropermanent magnet in response to the net magnetic field of the electropermanent magnet being in the activated state.
