Low-frequency vibration energy harvesting is more of a challenge, which can be solved by local resonance phononic crystals (LRPnCs). A novel three-dimensional (3D) energy harvesting LRPnC is proposed and further analyzed using the finite element method (FEM) software COMSOL. The 3D LRPnC with spiral unit-cell structures is constructed with a low initial frequency and wide band gaps (BGs). According to the large vibration deformation of the elastic beam near the scatterer, a PZT sheet is mounted in the surface of that beam, to harvest the energy of elastic waves using the PZT effect. To further improve the energy-harvesting performance, a 5 \u00d7 5 super-cell is numerically constructed. Numerical simulations show that the present 3D super-cell PnC structure can make full use of the advantages of the large vibration deformation and the PZT effect, i.e., the BGs with a frequency range from 28.47 Hz to 194.21 Hz with a bandwidth of 142.7 Hz, and the maximum voltage output is about 29.3 V under effective sound pressure with a peak power of 11.5 \u00b5W. The present super-cell phononic crystal structure provides better support for low-frequency vibration energy harvesting, when designing PnCs, than that of the traditional Prague type.<\/jats:p>","DOI":"10.3390\/s24020361","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T06:12:58Z","timestamp":1704694378000},"page":"361","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["An Investigation of the Energy Harvesting Capabilities of a Novel Three-Dimensional Super-Cell Phononic Crystal with a Local Resonance Structure"],"prefix":"10.3390","volume":"24","author":[{"given":"Hang","family":"Xiang","sequence":"first","affiliation":[{"name":"School of Mathematics and Computer Science, Northwest Minzu University, Lanzhou 730106, China"}]},{"given":"Zhemin","family":"Chai","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Wenzhou University, Wenzhou 325035, China"}]},{"given":"Wenjun","family":"Kou","sequence":"additional","affiliation":[{"name":"Experimental Teaching Department, Northwest Minzu University, Lanzhou 730000, China"}]},{"given":"Huanchao","family":"Zhong","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computer Science, Northwest Minzu University, Lanzhou 730106, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4028-985X","authenticated-orcid":false,"given":"Jiawei","family":"Xiang","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Wenzhou University, Wenzhou 325035, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1361","DOI":"10.1088\/1361-6463\/abe1e7","article-title":"Defect coupling behavior and flexural wave energy harvesting of phononic crystal beams with double defects in thermal environments","volume":"54","author":"Geng","year":"2021","journal-title":"J.
