Due to optimistic advancements in energy harvesting, there has been a consequential increase in MEMS energy harvesting systems. The enormous availability of low-frequency vibrations in the environment motivates researchers to convert them to usable electrical energy with reasonable efficiencies by implementing effective transduction procedures like piezoelectric, piezoresistive, capacitive, magnetic and thermomagnetic means. To reinforce this development, different structures of energy harvesters were modeled and simulated for its performance characteristics. In this research article, a piezoelectric ZnO nanowire-based energy harvesting system is considered and its usefulness was analysed for different performance metrics. The analysis results have shown that the modeled energy harvester does not succumb to fracture at low-frequency vibrations. The proposed nanowire energy harvester produced a power density of 1.45 W/m 2 when subjected to low-frequency vibrations. Moreover, the maximum von-Mises stress observed was at 50 Hz which lies in the low-frequency vibration level thereby making a promising effect of scavenging maximum power.
