Current studies have mostly focused on the harvesting capacity of piezoelectric harvesters under various conditions, and have given less attention to the electromechanical characteristics that are, in fact, crucial to a deeper understanding of the intrinsic mechanism of piezoelectric harvesting. In addition, the current related models have mostly been suitable for harvesting systems with very specific parameters and have not been applicable if the parameters were vague or unknown. Drawing on the available background information, in this study, we conduct research on a vibration-based cantilever beam of composite-laminated piezoelectric patches through an experimental study of its characteristics as well as a modeling study of energy harvesting. In the experimental study, we set out to investigate the harvesting capacity of the system, as well as the electromechanical (voltage\/current-strain and power-strain relationships) characteristics of the cantilever harvester. In addition, we summarize some pivotal rules with regard to several design variables, which provide configuration design suggestions for maximizing energy conversion of this type of harvesting system. In the modeling study, we propose a coupled electromechanical model with a set of updated parameters by using an optimization program. The preceding experimental data are used to verify the superiority of the model for accurately predicting the amount of harvested energy, while effectively imitating the characteristics of a cantilever harvesters. The model also has merit since it is suitable for diversified harvesters with vague or even unknown parameters, which cannot be dealt with by using traditional modeling methods. Overall, the experimental study provides information on a comprehensive way to enhance the harvesting capacity of piezoelectric cantilever transducers, and the modeling study provides a wide scope of applications for cantilever harvesters even if precise information is lacking.<\/jats:p>","DOI":"10.3390\/s22124457","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T02:01:44Z","timestamp":1655085704000},"page":"4457","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Versatile Model for Describing Energy Harvesting Characteristics of Composite-Laminated Piezoelectric Cantilever Patches"],"prefix":"10.3390","volume":"22","author":[{"given":"Xiaomin","family":"Xue","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Qing","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Qiangli","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Jiajia","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"045039","DOI":"10.1088\/0964-1726\/23\/4\/045039","article-title":"Analytical modeling and experimental validation of a structurally integrated piezoelectric energy harvester on a thin plate","volume":"23","author":"Aridogan","year":"2014","journal-title":"Smart Mater.
