Currently, researchers have started analyzing small-scale energy scavengers for the supply of energy in low-power electrical appliances. One area of interest is the use of piezoelectric materials, especially in the presence of mechanical vibrations. This study analyzed a unimorph cantilever beam in different modes by evaluating the effects of various parameters, such as geometry, piezoelectric material, lengths of layers, and the proof mass to the energy harvesting process. The finite element method was employed for analysis. The proposed model was designed and simulated in COMSOL Multiphysics, and the output parameters, i.e., natural frequencies and the output voltage, were then evaluated. The results suggested a considerable effect of geometrical and physical parameters on the energy harvesters and could lead to designing devices with a higher functional efficiency.<\/jats:p>","DOI":"10.3390\/s21248463","type":"journal-article","created":{"date-parts":[[2021,12,20]],"date-time":"2021-12-20T02:40:32Z","timestamp":1639968032000},"page":"8463","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Analysis of Energy Harvesting Enhancement in Piezoelectric Unimorph Cantilevers"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7594-6237","authenticated-orcid":false,"given":"Mohammad","family":"Rahimzadeh","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Golestan University, Gorgan 4913815759, Iran"}]},{"given":"Hamid","family":"Samadi","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Babol University of Technology, Babol 4714873113, Iran"}]},{"given":"Nikta Shams","family":"Mohammadi","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Shahrood University of Technology, Shahrood 3619995161, Iran"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1002\/er.5816","article-title":"Energy harvesting in wireless sensor networks: A taxonomic survey","volume":"45","author":"Singh","year":"2021","journal-title":"Int.
