Piezoelectric microelectromechanical systems (PiezoMEMS) make the production of self-contained microsystems of the next decade appealing. PiezoMEMS promises to remove expensive micro sensor-micro-systems assembly and have separate charging methods for batteries, while getting us closer to wireless systems and networks of battery-free sensors. A fully integrated energy harvester with a coin order of one quarter (diameter = 24.26 mm and thickness = 1.75 mm) can yield around 100 μW continuous to achieve practical application of this technology. Low-frequency environmental vibration power (below 100 Hz). This paper discusses the new state-of-the-art piezoelectric energy harvesting and summarizes key measurements such as the power density and bandwidth of recorded low-frequency input structures. This paper further outlines advances in piezoelectric materials and architectures of the resonator. In order to achieve much higher energy conversion efficiency epitaxial growth and grain texture of piezoelectric materials is being produced. The MEMS processes for these emerging materials groups are being studied for the production of lead-free, piezoelectric thin films in embedded health systems. Nonlinear resonance beams for broad bandwidth resonance are also tested, as they allow the energy harvesters to work high bandwidth and low frequency. The techniques of spraying on particles/granules are being matured to achieve meso-scale structures in a quick manner, such as aerosol deposition (AD) and granulum spray in vacuum (GSV). A power distribution circuit, which is another critical aspect of an energy harvester. To this end, the dissipation of minimum power is key to an energy harvester's small-scale power control circuit, requiring special circuit design techniques and a basic optimum power point traction. Overall, research and technological advancement took the science of energy harvesting closer in the near future to the practical applications.
