With the continually growing demand for electricity, it has become a “lifeline for human population,” and the rising disparity between its supply and demand, paved way to exploring alternative sources of energy, as well as its sustainable use, and “methods of electrical power generation that does not negatively impact the environment” as burning fossil fuels.
(Diamond, 2009) Much of its role in alternative energy and applications but first, what is piezoelectricity or, the piezoelectric effect? Wayne Tomasi (2004) defines the piezoelectric effect as generating electrical oscillations as varying mechanical stresses—either as, compression, tension, torsion or shearing, is applied across a crystal lattice structure (i.e. quartz, Rochelle salts, tourmaline, etc.) and vice versa. With this, ambient vibrations in and around systems which typically, are lost energy, can be captured and converted to usable energy, available for consumption—the primary goal of power harvesting; but since, as shown in research, the energy generated by piezoelectricity is insufficient to power most electronics, power harvesting technology has, mostly, focused on accumulation and storage techniques that would enable technology to collect enough energy for a variety of applications. ...
