Novel design, analytical and experimental studies of spring comprised Piezo electric energy harvester

Abstract

In this paper investigated a design of Spring-comprised Piezoelectric Energy Generator (SPEG) for random vibration , modelled and analyzed . The work basically focuses a novel spring comprised piezoelectric energy harvester with hitting masses, which is capable of harvesting energy from the ambient vibration. By properly designing the parameters, such as the length, diameter and mass of the shell and hitting masses, we can increase energy generated. For finding these parameters we carried out parametric analysis in SIMULINK. The main aim of the research is to get maximum voltage & power output. Analysis is carried out by varying the stiffness of spring and support excitation. Based on the analysis design of SPEG have been done and conducted experiments on the vibration shaker with a resonance frequency of 50 Hz at support displacement is 50 mm and developed a voltage of 18 volts as a output.
