Abstract: The power generation efficiency is to be enhanced by converting vibration energy including various direction components into electric energy without waste. A cantilever structure is adopted, in which a first plate-like bridge portion (120) and a second plate-like bridge portion (130) extend in a shape of a letter U from a fixing-portion (110) fixed to the device housing (200) and a weight body (150) is connected to the end. On the upper surface of the cantilever structure, a common lower layer electrode (E00), a layered piezoelectric element (300) and discrete upper layer electrodes (Ex1 to Ez4) are formed. The upper layer electrodes (Ez1 to Ez4) disposed on a center line (Lx, Ly) of each plate-like bridge portion take out charge generated in the piezoelectric element (300) due to deflection caused by the Z-axis direction vibration of the weight body (150). The upper layer electrodes (Ex1 to Ex4, Ey1 to Ey4) disposed on both sides of the center line (Lx, Ly) of the plate-like bridge portion take out charge generated in the piezoelectric element (300) due to deflection caused by the X-axis or Y-axis direction vibration of the weight body (150).

The transducer includes: a stationary member; at least two connecting members and two or more energy-conversion elements disposed on each connecting member. Each connecting member is attached at one location thereof to one of the stationary member or a second connecting member and, in response to a stimuli, is free to move along any of three geometric axes that are perpendicular to each other. Each energy-conversion element operates to convert motion of the connecting member to electrical energy or vice versa. A common geometric plane passes through each of the at least two connecting members and the stationary member, and the two largest dimensions of each connecting member defines a geometric plane that is parallel with the common geometric plane.

Abstract: A miniature energy harvesting device for producing electricity from acoustical energy, stray electromagnetic energy, noise and from energy of different anatomical motions. The device comprises a housing, a mechanical spring engaged with the housing between a static and dynamic state and a first magnet engaged with the mechanical spring. The device further comprises a conductive grid freely moveable within a cavity of the housing. The device further comprises a composite structure comprising a fixed magnet and a piezoelectric material. The composite structure is engaged with the grid and in communication with the first magnet. The first magnet and the fixed magnet apply a force upon the piezoelectric material when the mechanical spring is in the static state to produce a base voltage. Excitation of the mechanical spring causes the piezoelectric material to generate an alternating voltage output having a peak voltage greater than the base voltage.

Abstract: An energy harvesting device utilizing a monolithic, mesoscale, single-degree-of-freedom inertial based resonator in which the support structure, beam-spring, and proof mass are a single component without joints, bonds, or fasteners. Frequency tuning features include holes in the proof mass in which mass can be added to change the devices resonance frequency as well as levers which add curvature to the beam-spring system and adjust system stiffness. Robustness is increase by designing the resonator to exhibit nonlinear behavior such that its power density is maximized for low vibration amplitudes and minimized for high amplitudes. The device structural resonance modes are designed to be much higher than the resonators proof mass-spring resonance frequency. Electromechanical transducers are used to convert the resonators mechanical energy to electrical energy. Electrical circuitry is included to extract and condition the electrical charge.
