Title: Electrostatic Actuator
Inventor: TIM HELPS
IPC: H02N1/00
Filed: 2017-06-29
Abstract: An electrostatic actuator 10 comprises a first electrode 12, a second flexible or arcuate electrode 14, and an insulator 16 that inhibits electrical coupling between the electrodes. The electrodes are mechanically coupled via a first coupling 18 at one end to define a free portion of the second electrode that can move between close and spaced positions with respect to the first electrode. The first coupling defines a first zipping crevice (ZC, figure 2) at a region where the second electrode transitions from being at a first distance from the first electrode, equivalent to the thickness of the insulator, to a second distance larger than the first distance. A mobile dielectric 19 is located within the first crevice and moves with it as it propagates along the actuator due to flexing or movement of the second electrode towards the first electrode. The dielectric may be a bead of dielectric liquid, which may move into and out of a reservoir 15 provided in one or each electrode or the insulator. The second electrode may be coupled to the first electrode via second coupling (22, figure 4) to define a second zipping crevice in which is provided a second dielectric. The free portion of the second electrode may be defined between the two couplings.
