Piezoelectric Energy Harvesting: A Systematic Review of Reviews

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.

Application to Piezoelectric and Triboelectric Generators of Spongy Structured BaTiO3 Prepared by Sputtering

“…관련 기술중 압전 및 마찰전기 효과를 사용한 에너지 하베스팅에 대한 연구가 최근 활발하게 진행되고 있다. 압전 [1][2][3][4][5][6] 및 마찰 전기 [7][8][9][10][11] [12][13][14][15] 가 있는데 세계적으로 납사용을 규제하면서 최근에는 BaTiO 3 (BTO), 16,17) ZnO 18) 및 PVDF (polyvinylidene difluoride)…”

Available Technologies and Commercial Devices to Harvest Energy by Human Trampling in Smart Flooring Systems: A Review

“…The cymbal and bridge are the most common designs for piezoelectric harvesters [23]. Ceramic piezoelectric transducers are relatively fragile; in fact, they can be destroyed when exposed to energy produced from human motions [24,25]. Nowadays, there are different structures of piezoelectric generators; in particular, they are classified into two categories:…”

A Contactless Coupled Pendulum and Piezoelectric Wave Energy Harvester: Model and Experiment

“…Therefore, vibration-frequency-increasing piezoelectric wave energy converters (pWECs) have become a popular topic recently [23,24]. A comprehensive review of the state-of-the-art research on pWECs can be found in [25,26]. Mechanical contacts and magnetic impacts are commonly used vibration-frequency-increasing conversion techniques for piezoelectric cantilever beams.…”
