Abstract
A multifunctional haptic actuator having actuation modes, including an actuation arrangement and at least one moveable energy storage. The actuation arrangement provides and facilitates movement of the energy storage along and around actuation axes. The energy storage supplies electric charge to drive the actuation arrangement, and stores electric charge generated by the actuation arrangement. A first functional actuation mode includes generating mechanical vibrations by supplying electric charge from the energy storage to the actuation arrangement, the electric charge generating movement of the energy storage. A second functional actuation mode includes generating electric charge by mechanical vibrations of the energy storage, the vibrations generating electric charge in the actuation arrangement, the electric charge being stored in the energy storage.
