Li, Chenchen (author), Yang, Fan (author), Liu, Pengfei (author), Fu, Chaoliang (author), Liu, Quan (author), Zhao, Hongduo (author), Lin, P. (author)To improve the energy harvesting efficiency of the piezoelectric device, a stack units-based structure was developed and verified. Factors such as stress distribution, load resistance, loads, and loading times influencing the piezoelectric properties were investigated using theoretical analysis and experimental tests. The results show that the...journal article 2021
