With a high electromechanical conversion rate and high bearing capacity, the stack piezoelectric transducer is one of the most used structures in road energy harvesting to convert mechanical energy into electrical energy. To further improve the energy generation efficiency of this type of piezoelectric energy harvester (PEH), this study theoretically and experimentally investigated the influences of connection mode, number of stack layers, ratio of height to cross-sectional area and number of units on the power generation performance. Two types of PEHs were designed and verified using a laboratory accelerated pavement testing system. The findings of this study can guide the structural optimization of PEHs to meet different purposes of sensing or energy harvesting.<\/jats:p>","DOI":"10.3390\/s21082876","type":"journal-article","created":{"date-parts":[[2021,4,20]],"date-time":"2021-04-20T05:35:25Z","timestamp":1618896925000},"page":"2876","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Development of Piezoelectric Energy Harvester System through Optimizing Multiple Structural Parameters"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3188-2013","authenticated-orcid":false,"given":"Hailu","family":"Yang","sequence":"first","affiliation":[{"name":"National Centre for Materials Service Safety, University of Science &amp; Technology Beijing, Beijing 100083, China"},{"name":"Research and Development Center of Transport Industry of New Materials, Technologies Application for Highway Construction and Maintenance, Beijing 100088, China"}]},{"given":"Ya","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Tsinghua University, Beijing 100083, China"}]},{"given":"Weidong","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Centre for Materials Service Safety, University of Science &amp; Technology Beijing, Beijing 100083, China"}]},{"given":"Yibo","family":"Ai","sequence":"additional","affiliation":[{"name":"National Centre for Materials Service Safety, University of Science &amp; Technology Beijing, Beijing 100083, China"},{"name":"Innovation Group of Marine Engineering Materials and Corrosion Control, Southern Marine Science and Engineering Guangdong Laboratory, Zhuhai 519080, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8115-1780","authenticated-orcid":false,"given":"Zhoujing","family":"Ye","sequence":"additional","affiliation":[{"name":"National Centre for Materials Service Safety, University of Science &amp; Technology Beijing, Beijing 100083, China"}]},{"given":"Linbing","family":"Wang","sequence":"additional","affiliation":[{"name":"Joint USTB Virginia Tech Lab Multifunctional Materials, USTB, Department Civil &amp; Environmental Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"465","DOI":"10.1016\/j.carbon.2019.11.013","article-title":"Performance evaluation of bitumen with a homogeneous dispersion of carbon nanotubes","volume":"158","author":"Yang","year":"2020","journal-title":"Carbon"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"119768","DOI":"10.1016\/j.jclepro.2019.119768","article-title":"Study on the reinforcement effect and the underlying mechanisms of a bitumen reinforced with recycled glass fiber chips","volume":"251","author":"Yang","year":"2020","journal-title":"J.
