Multifunctional haptic actuator

A multifunctional haptic actuator having a plurality of functional actuation modes, the multifunctional haptic actuator comprising:

• an actuation arrangement;
• and
• at least one moveable energy storage,
• wherein the actuation arrangement is configured to provide or facilitate movement of the energy storage along or around a plurality of actuation axes,
• wherein the energy storage is configured to supply electric charge to drive the actuation arrangement, and is configured to store electric charge generated by the actuation arrangement,
• wherein the functional actuation modes comprise a first functional actuation mode wherein the multifunctional haptic actuator is configured to generate mechanical vibrations by supplying electric charge from the energy storage to the actuation arrangement, the electric charge being configured to generate movement of the energy storage, and
• wherein the functional actuation modes further comprise a second functional actuation mode wherein the multifunctional haptic actuator is configured to generate electric charge by mechanical vibrations of the energy storage, the mechanical vibrations being configured to generate electric charge in the actuation arrangement, the electric charge being configured to be stored in the energy storage.
