Abstract

The work proposes a novel piezoelectric energy harvester (PEH) based on the seesaw mechanism. The seesaw structure has been utilized in PEH for extracting a wide range of ambient vibrations and converting them into usable electrical energy. The proposed structure operates on the first two resonant frequencies in comparison to the conventional cantilever system that works on the first resonant frequency. Eigen frequency, as well as response to a varying input vibration frequency, is carried out showing better performance of seesaw cantilever design. The harvester efficiently converts mechanical energy into electrical energy while reaching a power output of 0.55 mW with a wider band of operation.
