A Self‐Regulated Piezoelectric Wind Energy Harvesting Device Driven by Combined Centrifugal and Gravitational Effects
A self‐regulating piezoelectric wind energy harvester (CSG‐PEH) is proposed to address the low efficiency, narrow operating range, and limited durability of conventional piezoelectric wind energy harvesters (PWEHs). The device incorporates a centrifugal spring mechanism (CSM), in which centrifugal force and elastic for...
