    Abstract: Embodiments of making an energy harvesting device (300) are described. In one embodiment, a case (310, 308, 306) and integrated piezoelectric cantilever (302) to harvest vibration energy from an environment being sensed is produced via a print forming method injection molding method. The cantilever device consists of a piezoelectric material member, and a proof mass of high density material coupled to the piezoelectric member. The print forming method is used to build up the base and walls of the device as well as the neutral layers of the piezoelectric member. Metal layers are printed to form the electrode layers of the piezoelectric member and the electrical contact portions of the device. Passive components can also be formed as part of the layers of the device The entire assembly can be encapsulated in plastic.

    Abstract: Many inventions are disclosed. Some aspects are directed to MEMS, and/or methods for use with and/or for fabricating MEMS, that supply, store, and/or trap charge on a mechanical structure disposed in a chamber. Various structures may be disposed in the chamber and employed in supplying, storing and/or trapping charge on the mechanical structure. In some aspects, a breakable link, a thermionic electron source and/or a movable mechanical structure are employed. The breakable link may comprise a fuse. In one embodiment, the movable mechanical structure is driven to resonate. In some aspects, the electrical charge enables a transducer to convert vibrational energy to electrical energy, which may be used to power circuit(s), device(s) and/or other purpose(s). In some aspects, the electrical charge is employed in changing the resonant frequency of a mechanical structure and/or generating an electrostatic force, which may be repulsive.

    Abstract: A low temperature method for forming a microcavity on a substrate and article having same are provided which utilize electroplated films. The method is particularly useful to package microelectromechanical systems (MEMS) in vacuum on the wafer level and provide sealed feedthroughs to the outside world. The method may be performed in a batch process to substantially reduce cost and to form metal diaphragms. Furthermore, the method is performed at near room temperature, which provides more flexibility in the manufacturing process. The method enables substantial cost savings in the production of vacuum-sealed MEMS. Many feedthroughs can be incorporated into the package to transfer signals in and out of the package. One significant advantage of this method is that it does not require bonding of a second substrate, which reduces the system cost.
