TL;DR: In this paper, a High Efficiency MEMS Micro-Vibrational Energy Harvester (μVEH) has been proposed, which is capable of producing a voltage of sufficient magnitude such that the requirement to connect a plurality of harvesters in series to produce an adequate voltage magnitude is eliminated.
Abstract: The present invention relates generally to a High Efficiency MEMS Micro- Vibrational Energy Harvester (μVEH) having an thick beam bimorph architecture. The disclosed architecture is capable of producing a voltage of sufficient magnitude such that the requirement to connect a plurality of harvesters in series to produce an adequate voltage magnitude is eliminated.

TL;DR: In this paper, a piezoelectric bimorph transducer utilizing the d33 coefficient was developed, which consists of polymeric segments bonded by a polymeric agent and fabricated by a dicing and layering technique.
Abstract: A piezoelectric bimorph transducer utilizing piezoelectric d33 coefficient was developed. This bimorph consists of piezoelectric segments bonded by a polymeric agent and was fabricated by a dicing and layering technique. The transducer has superior piezoelectric characteristics compared to standard piezoelectric d31 bimorphs. Piezoelectric coefficients, electrical admittance, mechanical compliance, and losses of the actuator were found to increase with increasing driving electric field.

TL;DR: In this article, focused ion beam (FIB) technology was used to fabricate thermally actuated cantilever arrays using silicon nitride membrane chips for microelectromechanical systems (MEMS) applications.
Abstract: Focused ion beam (FIB) technology was used to fabricate thermally actuated cantilever arrays using silicon nitride membrane chips for microelectromechanical systems (MEMS) applications. Sequential modification and test is made possible by the dualbeam FIB/SEM. A fabrication route based largely on the use of FIB etch and deposition steps applied to a silicon nitride membrane chip resulted in the formation of readily released bimorph structures with lengths

17 May 1993TL;DR: In this paper, a container (10) for compressed gas with a pressure relief member (18) made from a bimorph shape memory material is described, which is impermeable by the gas.
Abstract: A container (10) for compressed gas with a pressure relief member (18) made from a bimorph shape memory material. The bimorph (18) is impermeable by the gas. The bimorph (18) assumes a shape which changes depending on temperature. Below a critical temperature, the bimorph (18) lies in a first (deformed) state, and reverts to a second (remembered) state thereabove. The gas is entrapped within the container (10) when the bimorph (18) assumes the first state. When pressure rises due to temperature increase above the critical temperature, gas may escape from the container (10). This is because the bimorph (18) reverts to its second state, in which a relief gas passageway is opened, thereby relieving gas pressure.
