This device consists of a leaf spring and eight pairs of piezoelectric layers attached to inner and outer surfaces. We present a special type of leaf spring, which can magnify the force from the workload to allow the piezoelectric layers to achieve larger deformation. The generator is to solve the problem of vibration energy reutilization in a low-frequency vibration system. To verify the efficiency of the proposed configuration, a series of experiments are operated. The results indicate that the resonance frequency (25.2 Hz) obtained from the sweep experiment is close to the simulation result (26.1 Hz). Impedance-matching experiments show that the sum of the output power attains 1.7 mW, and the maximum single layer reaches 0.6 mW with an impedance matching of 610 K\u03a9, and the instantaneous peak-peak power density is 3.82 mW\/cm3. The capacitor-charging performance of the generator is also excellent under the series condition. For a 4.7 \u03bcF capacitor, the voltage is charged to 25 V in 30 s and limited at 32 V in 80 s. These results demonstrate the exploitable potential of piezoelectric energy harvesting from suspension structures.<\/jats:p>","DOI":"10.3390\/s20133755","type":"journal-article","created":{"date-parts":[[2020,7,6]],"date-time":"2020-07-06T13:49:11Z","timestamp":1594043351000},"page":"3755","source":"Crossref","is-referenced-by-count":8,"title":["Piezoelectric Energy Harvesting from Suspension Structures with Piezoelectric Layers"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"http:\/\/orcid.org\/0000-0003-1756-1405","authenticated-orcid":false,"given":"Min","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Yiming","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Huayan","family":"Pu","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-8019-6765","authenticated-orcid":false,"given":"Yi","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Jiheng","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"},{"name":"Shanghai Institute of Intelligent Science and Technology, Tongji University, Shanghai 200092, China"}]},{"given":"Jun","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Shaorong","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Yan","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"given":"Quan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-3570-3286","authenticated-orcid":false,"given":"Zhongjie","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai 200444, China"},{"name":"Shanghai Institute of Intelligent Science and Technology, Tongji University, Shanghai 200092, China"},{"name":"Department of Mechanical and Industrial Engineering, University of Toronto, Toronto, ON M5S 3G8, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"043001","DOI":"10.1088\/0964-1726\/17\/4\/043001","article-title":"Powering MEMS portable devices\u2014A review of non-regenerative and regenerative power supply systems with special emphasis on piezoelectric energy harvesting systems","volume":"17","author":"Thambi","year":"2008","journal-title":"Smart Mater.
