This paper proposes a novel energy harvesting floor structure using piezoelectric elements for converting energy from human steps into electricity. The piezoelectric energy harvesting structure was constructed by a force amplification mechanism and a double-layer squeezing structure in which piezoelectric beams were deployed. The generated electrical voltage and output power were inve... https://herbsdailyes.shop/product-category/medical-and-ambulatory-supplies-nutritionals-and-feeding-supplies/
