Energy harvesting using piezoelectric materials is not a new concept, but its small generation capability has not been attractive for mass energy generation. For this reason, little research has been done on the topic. Recently, increased interest in wearable computer concepts and remote electrical devices has provided motivation for more extensive study of piezoelectric energy harvesting. The theory behind cantilever-type piezoelectric elements is well known, but the transverse moving plate elements, which can be used in energy generation from pressure sources is not yet fully developed. The power generation in a pressure-loaded plate depends on several factors. Among them, the thickness of each layer is important, as is the electrode pattern used. In this article, two clamped circular plate structures, a fully electroded unimorph, and a so-called regrouped electrode unimorph, are modeled. These models are then used to calculate energy generation with varying thickness ratios. The results of this analysis are presented with an eye toward guidelines for design of useful energy harvesting structures.

“…Excitations could be in the form of applied load, pressure, or vibration. Some example applications for which this has been studied include various loading conditions, such as impact (Xu et al, 1996(Xu et al, , 1998 and resonance (Goldfarb and Jones, 1999), human movement (Schmidt, 1992;Kymissis et al, 1998;Shenck, 1998), and acoustic energy (Mandurino et al, 2001).…”

In a companion article, a model for a clamped circular unimorph piezoelectric plate has been developed for the purpose of analyzing the influence of geometric design parameters and electrode configuration on the amount of electrical energy that can be harvested from an applied pressure source. It has been shown that the ratio of layer thickness (piezoelectric layer to substrate layer) and electrode pattern have a significant effect on energy conversion for harvesting. Specifically, the theoretical analysis shows that regrouping of the electrodes (i.e., segmenting the electrode into a specific pattern) can lead to optimized energy harvesting in a clamped circular plate structure. This article provides experimental validation of these results. In this article, three circular plate piezoelectric energy generators (PEGs), one unmodified and two regrouped unimorph PEGs, were used to support the analysis.
