Abstract

In the last decade, an enormous amount of attention has been paid to piezoelectric harvesters due to their flexibility in design and the increasing need for small-scale energy generation. As a result, various energy review papers have been presented by many researchers to cover different aspects of piezoelectric-based energy harvesting, including piezo-materials, modeling approaches, and design points for various applications. Most of these papers have tried to shed light on recent progress in related interdisciplinary fields, and to pave the road for future prospects in the development of these technologies. However, there are some missing parts, overlaps, and even some contradictions in these review papers. In the present review of these review articles, recommendations for future research directions suggested by the review papers have been systematically summed up under one umbrella. In the final section, topics for missing review papers, concluding remarks on outlooks and possible research topics, as well as potentially misleading strategies, have been presented. The review papers have been evaluated based on their merits and subcategories and the authors’ choice papers have been presented for each section based on clear classification criteria.

Highlights

  • Due to recent developments in portable and wearable electronics, wireless electronic systems, implantable medical devices, energy-autonomous systems, monitoring systems, and MEMS/NEMS-based devices, the procedure of small-scale energy generation may lead to a revolution in the development of compact power technologies

  • The number of review papers on piezoelectric energy harvesting has extensively increased in the past decade

  • Brenes et al [34] provided an overview of existing energy harvesting circuits and techniques for piezoelectric energy scavenging to distinguish between similar existing solutions that are different in practice

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. The number of review papers on piezoelectric energy harvesting has extensively increased in the past decade. We tried to summarize all deficits, advantages, and missing parts of the existing review papers on piezo-energy harvesting systems. An extensive search among database sources identified 91 review papers in diverse applications related to piezoelectric energy harvesting. Due to the interdisciplinary nature of piezoelectric energy harvesting, predicting the behavior of piezo-generators is related to different thermo-electro-mechanical sciences, as well as material engineering. Different branches of connected sciences and applications include fabrication methods, hybrid systems, performance evaluation, size, utilization methods, configurations, modeling aspects, economic points, energy sources, optimization, the design of an electric interface, and the selection of proper materials. 1 point for the number of sub-categories covered, 2 points for paying attention to merits, and 1 point for reporting the minimum required energy output level. A summary of future challenges, research directions, and missing review topics is presented
