TL;DR: In this article, a MEMS-based PZT/PZT thick film bimorph vibration energy harvester with an integrated silicon proof mass is presented, which replaces the support with another layer of the piezoelectric material, and with the absence of an inactive mechanical support all of the stresses induced by the vibrations will be harvested by the active PZE elements.

TL;DR: In this paper, the authors describe the fabrication and characterization of a significantly improved version of a microelectromechanical system-based PZT/PZT thick film bimorph vibration energy harvester with an integrated silicon proof mass.

TL;DR: In this article, the authors revisited the standard electromechanical model by focusing on the impedance of the piezoelectric device, leading to simple closed form expressions for peak power frequency, optimal load, and output power without a tedious mathematical derivative approach.

TL;DR: An energy harvesting unit consisting of a base and a lid, the package including a sealed interior volume and an exterior, a ledge formed in the sealed interior with a first cavity above and a second cavity below the ledge, a plurality of inner electrical contacts formed on the ledge; a pluralityof outer electrical contacts forming on the exterior of the package, and a piezo-electric member in electrical communication with the inner electrical contact and coupled to the ledge on a first side of a package and spanning across the cavity and coupling to the lip on an opposite side of package.

TL;DR: In this article, the authors describe fabrication and characterization of a significantly improved version of a MEMS-based PZT/PZT thick film bimorph vibration energy harvester with an integrated silicon proof mass.
