To improve the power conversion capability, a piezoelectric beam with different electrode coverage ratios is studied theoretically and experimentally in this paper. A distributed-parameter theoretical model is established for a bimorph piezoelectric beam with the consideration of the electrode coverage area. The impact of the electrode coverage on the capacitance, the output power and the optimal load resistance are analyzed, showing that the piezoelectric beam has the best performance with an electrode coverage of 66.1%. An experimental study was then carried out to validate the theoretical results using a piezoelectric beam fabricated with segmented electrodes. The experimental results fit well with the theoretical model. A 12% improvement on the Root-Mean-Square (RMS) output power was achieved with the optimized electrode converge ratio (66.1%). This work provides a simple approach to utilizing piezoelectric beams in a more efficient way.<\/jats:p>","DOI":"10.3390\/s18030804","type":"journal-article","created":{"date-parts":[[2018,3,7]],"date-time":"2018-03-07T12:55:23Z","timestamp":1520427323000},"page":"804","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Electrode Coverage Optimization for Piezoelectric Energy Harvesting from Tip Excitation"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7557-3853","authenticated-orcid":false,"given":"Hailing","family":"Fu","sequence":"first","affiliation":[{"name":"Department of Aeronautics, Imperial College London, Exhibition Road, London SW7 2AZ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangzhu","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Nuclear Technology and Automation Engineering, Chengdu University of Technology, Chenghua District, Chengdu 610059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Bai","sequence":"additional","affiliation":[{"name":"College of Nuclear Technology and Automation Engineering, Chengdu University of Technology, Chenghua District, Chengdu 610059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1457","DOI":"10.1109\/JPROC.2008.927494","article-title":"Energy Harvesting From Human and Machine Motion for Wireless Electronic Devices","volume":"96","author":"Mitcheson","year":"2008","journal-title":"Proc.
