摘要: A dielectric actuator including an enclosure forming a cavity having a dielectric fluid therein, the enclosure having a base, a flexible membrane and a reversibly-stretchable membrane, and a pair of electrodes, one electrode of the pair of electrodes arranged at the flexible membrane, the other electrode arranged at the base, the pair of electrodes arranged to generate an electric field to an area of the cavity that is filled with the dielectric fluid, wherein when the electric field is generated between the pair of electrodes, an electrostatic pressure in the dielectric fluid causes the flexible membrane to move towards the base, reducing an initial volume of the area of the cavity, increases a pressure of the dielectric fluid inside the cavity, and causes the reversibly-stretchable membrane to bump out to an expanded state.

摘要: The present invention concerns an electromagnetic actuator for a haptic display. The actuator comprises: a) a first, movable permanent magnetic element, the first magnetic element comprising a first latching layer facing side, a second latching layer facing side substantially opposite to the first latching layer facing side, and at least one lateral face between the first latching layer facing side and the second latching layer facing side; b) a shielding element for shielding laterally the first magnetic element to confine a magnetic field generated by the first magnetic element; c) a first actuation inductor facing the first latching layer facing side for actuating the first magnetic element and arranged to displace the first magnetic element from a first latching position to a second latching position, or vice versa; d) a first latching layer facing the first latching layer facing side and arranged to attract the first magnetic element for obtaining the first latching position; and e) a second latching layer facing the second latching layer facing side and arranged to attract the first magnetic element for obtaining the second latching position, different from the first latching position.
