Abstract:
Provided are a method for manufacturing a flexible nanogenerator and a flexible nanogenerator manufactured thereby. The method for manufacturing the flexible nanogenerator of the present invention includes the steps of: laminating a piezoelectric element layer having a piezoelectric material layer on a sacrificial substrate; crystallizing the piezoelectric element layer by thermally processing the piezoelectric element layer at a high temperature; separating unit piezoelectric elements from the sacrificial substrate by removing the sacrificial substrate; and transferring the separated unit piezoelectric elements onto a flexible substrate. The method for manufacturing the flexible nanogenerator and the flexible nanogenerator manufactured thereby of the present invention can continuously produce electric power from the movement of a human body and the like by producing electric power according to the bending of the substrate.
Abstract:
A curved multimorph actuator is provided composed of a plurality of materials, each material exhibiting different deformations in response to a stimulus, such as heat. Application of different stimuli causes the actuator to bend and/or twist. In an embodiment, the actuator is capable of rotating an object about its center without significantly shifting the center in one or more dimensions. In a further embodiment, the actuator can be used to rotate an object about a first axis and a second axis, wherein the first axis and the second axis are mutually perpendicular. In an embodiment, rotation about the first axis and the second axis are achieved in combination. In another embodiment, rotation about the first axis is produced in response to a first stimulus and rotation about the second axis is produced in response to a second stimulus.
Abstract:
A micro or nano electromechanical transducer device (200) formed on a semiconductor substrate comprises a movable structure (203) which is arranged to be movable in response to actuation of an actuating structure. The movable structure comprises a mechanical structure having at least one mechanical layer (204) having a first thermal response characteristic, at least one layer (202) of the actuating structure having a second thermal response characteristic different to the first thermal response characteristic, and a thermal compensation structure having at least one thermal compensation layer (206). The thermal compensation layer is different to the at least one layer (202) and is arranged to compensate a thermal effect produced by the mechanical layer and the at least one layer of the actuating structure such that the movement of the movable structure is substantially independent of variations in temperature.
Abstract:
A microactuator for displacing a platform vertically with respect to a substrate includes a first rigid frame, a first flexible bimorph beam connecting the first frame to the substrate, a second rigid frame, a second flexible bimorph beam connecting the second frame to the first frame, and a third flexible bimorph beam connecting a platform to the second frame. Activation of the first, second, and third flexible bimorph beams allows vertical displacement of the platform with respect to the substrate, with negligible lateral shift. A microactuator assembly includes a substrate, a plurality of first rigid frames, a plurality of first flexible bimorph beams, a plurality of second rigid frames, a plurality of second flexible bimorph beams, a platform, and a plurality of third flexible bimorph beams. Activation of the first, second, and third bimorph beams allows vertical displacement of the platform with respect to the substrate, with negligible lateral shift. A further embodiment with four identical such microactuators oriented at four sides of the platform, can achieve ID or 2D angular scanning of the mirror plate by the activation of 1 or 2 adjacent microactuators.
