Power optimization of a piezoelectric-based energy harvesting cantilever beam using surrogate model
Energy harvesting is a conventional method to collect the dissipated energy of a system. In this paper, we investigate the optimal location of a piezoelectric element to harvest maximum power concerning different excitation frequencies of a vibrating cantilever beam. The cantilever beam oscillates by a concentrated sinusoidal tip force, and a piezoelectric patch is integrated on the beam to gen...
متن کاملPiezoelectric Micro Power Generator for Energy Harvesting
A thin film lead zirconate titanate Pb(Zr,Ti)O3 (PZT), power generating device is developed. It is designed to resonate at specific vibrational frequencies from an ambient, vibrational energy source, thereby creating electrical energy via the piezoelectric effect. The energy harvesting device uses the piezoelectric d33 mode and is fabricated with three mask steps. Our cantilever device was desi...
متن کاملModel of Piezoelectric Power Harvesting Beam
Piezoelectric materials can be used as mechanisms to transfer mechanical energy, usually ambient vibration into electrical energy that can be stored and used to power other devices. With the recent advances in wireless and MEMS technology, sensors can be placed almost anywhere necessary. Since these devices are wireless it becomes necessary that they have their own power supply. This power supp...
متن کاملModeling and Optimal Design of Piezoelectric Cantilever Microactuators
A novel model is described for predicting the static behavior of a piezoelectric cantilever actuator with an arbitrary configuration of elastic and piezoelectric layers. The model is compared to deflection measurements obtained from 500m-long ZnO cantilever actuators fabricated by surface micromachining. Modeled and experimental results demonstrate the utility of the model for optimizing device...
متن کاملOptimal Design of Piezoelectric Materials for Maximal Energy Harvesting
The military’s dependence on fossil fuels for electric power production in isolated settings is both logistically and monetarily expensive. Currently, the Department of Defense is actively seeking alternative methods to produce electricity, thus decreasing dependence on fossil fuels and increasing combat power. We believe piezoelectric generators have the ability to contribute to military appli...
