Analysis on piezoelectric energy harvesting small scale device - a review

Due to advancement of auto regulated powered wireless sensors systems; piezoelectric pulsation energy harvesters (PVEHs) have received a significant attention. Though, a popular of these devices has very low input frequencies. This paper seeks to analyze the current method to harness energy from vibration using piezoelectric setup in the low range of frequency zone and demonstrate an experiment model to validate the results from the setup. Many reviewers have given different modelling approach to optimize the performance parameter such as mass ratio, damping constant, frequency, load resistance, electromechanical coupling constant and capacitance etc. Finally, it has been found from experimentally and simulation that the maximum power harvested from the piezoelectric vibration setup depends upon the maximum deflection of the beam subjected to many dynamic constraint parameters such as inertia of the beam, maximum lift force due to wind, and lift drag characteristics curve etc. (C) 2017 The Authors.
