Piezoelectric transducer portable#
mobiles, portable electronics or wireless sensors networks (Sodano et al., 2004b Pereyma, 2007 Anton and Sodano, 2007). The piezoelectric materials, in special PZTs, have been largely used as mechanisms to convert ambient motion, usually vibration, into electrical energy that may be stored or used directly to provide power to other devices, e.g. Keywords: smart structures, piezoelectric transducers, energy harvesting, rectifier circuit All tests and results are described and detailed using Matlab, the SimPowerSystem toolbox of the Simulink and an experimental setup. In order to illustrate the results, numerical simulations and experimental verifications are also performed to ensure the accuracy. A very simple and comprehensive description for choosing the capacitance and resistance loads is provided. The true electrical components were considered in the full-wave rectifier circuit with four diodes in bridge. In this sense, the goal of the present paper is to describe a comprehensive strategy for power harvesting device to estimate the output power provided by a cantilever beam with the electrodes of the piezoceramic layers connected to a standard rectifier circuit. In the real-world applications, the energy harvesting external circuit is more complex than a simple load resistance. Unfortunately, most of the models used focused on simplifying the energy harvesting circuit into a simple resistive load. For practical use of vibration energy harvester with piezoelectric materials, it is necessary to process the alternating current (AC) by using different rectifiers' circuits in order to charge batteries with direct current (DC) or to feed electronic devices. energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.
