Abstract: A thin-film device and a method of fabricating the thin-film device are provided herein. The thin-film device comprises a bond layer, a film layer that has bulk material properties, and a substrate that has a heat-sensitive component disposed thereon. The method of fabricating the thin-film device comprises the step of providing an active material that has bulk material properties. The active material is bonded to the substrate through the bond layer. After bonding the active material to the substrate, the active material that is bonded to the substrate is thinned to produce the film layer of the thin-film device. The substrate is provided with the heat-sensitive component disposed thereon prior to bonding the active material to the substrate.

Abstract: A liquid-gap electrostatic hydraulic micro actuator is provided that produces higher displacement (in and out of plane) and larger force than typical electrostatic actuators by utilizing a non-conducting liquid as its dielectric material. This new class of actuators utilizes the liquid dielectric for hydraulic amplification and force transfer. The liquid electrostatic actuator consists of two chambers each forming a parallel-plate capacitor, filled with a non-conducting incompressible liquid. One chamber is compressed by pulling down a flexible membrane using electrostatic actuation, thus forcing the liquid under it to transfer into the other chamber. Such movement causes the other chamber's membrane to expand out of plane.
