Abstract
Cantilever beam-based piezoelectric energy harvesters (PEHs) convert vibrational mechanical energy to electrical energy. The study by Huan Zhao, Xiangbei Liu, and Yan Li (see article number 2301214) demonstrates a substantial enhancement in the PEH performance – up to 13.26-fold – by replacing the conventional solid substrate with a 3D auxetic unit-cell metastructure. Computational analysis suggests that enhancing the performance of a unimorph PEH requires selecting a metastructure substrate with low stiffness. However, it is crucial to prevent mechanical loss caused by internal metastructure deformation, which impedes the effective transfer of deformation to the piezo patch.
