A FINITE ELEMENT METHOD EXPLORATION OF TECHNOLOGICALLY RELEVANT GEOMETRIES IN PIEZOELECTRIC ENERGY-HARVESTING PZT-4.

In a piezoelectric material, any external action that can generate a mechanical deformation could be a potential source of electrical energy. This phenomenon is studied for the development of microscale devices, using as external agents the hydraulic pressure of a fluid, the movement of human beings...

        In a piezoelectric material, any external action that can generate a mechanical deformation could be a potential source of electrical energy. This phenomenon is studied for the development of microscale devices, using as external agents the hydraulic pressure of a fluid, the movement of human beings and others. Nowadays, the main research efforts focus on optimizing the properties of developed piezoelectric materials and also to the simulation of different situations that allow the optimization of the energy harvesting devices. The present paper shows some simulations, which have been made by using the finite element method to simulate the energy harvesting; the results are presented for a commercial piezoelectric, PZT-4.
        En un material piezoeléctrico cualquier acción externa que pueda generar una deformación mecánica puede ser una potencial fuente de energia eléctrica. Este fenómeno se estudia para el desarrollo de dispositivos en la microescala, utilizando como agentes externos, entre otros, la presión hidráulica de un fluido o el propio movimiento del ser humano. Las investigaciones actualmente están dirigidas, por una parte a la optimización de las propiedades de los materiales que se desarrollan para tales fines, y por otro lado, a la simulación en diferentes escenarios que permitan optimizar los dispositivos a desarrollar. En este trabajo presentamos algunas simulaciones, empleando el método de elementos finitos, para la recolección de energía piezoeléctrica; se presentan los resultados para un piezoeléctrico comercial, PZT-4.
