Abstract
This paper is a numerical and experimental analysis of the behavior of piezoelectric disks inserted between two plates subjected to different loads and induced vibrations. There are many studies of harvesting energy systems, that are considered one of the most promising researches for cleanable and renewable energy. Among sources such as solar energy, wind, temperature gradients, antenna and microwave, the vibration stands out for the transformation of mechanical energy into electric energy with piezoelectric materials. Piezoelectric systems are already being installed around world to take advantage of this kind of energy and with the improvement of your efficiency, it can be used in large scale for energy transduction. The objective of this work is to verify the behavior of the piezoelectric plates in different circumstances to make easier the development of new energy pickups using this type of technology. To achieve this goal, was developed a mathematical model for a numerical analysis of the behavior of the disks observing the stability of the system, and then an experimental analysis was produced where measurements were made of the energy released by the piezoelectric when they were under the influence of an initial vibration and when they were submitted to different loads. As a result a great influence was found between the compression loads and initial vibrations with the voltage output by the system.
