Caracterización de Parámetros Eléctricos de los Piezoeléctricos PZT y PVDF Utilizados en el Mercado Colombiano

Abstract

In order to fulfill the general objective of the project, which was established as: characterize the behavior of the electric variables of the piezoelectric PZT and PVDF acquired in the Colombian market, the project was divided in four stages (Bibliographic consultation, selection of the piezoelectric technology, experimental design and mathematical tests and analysis), which led to an important result, which reflects that the increase in temperature in the environment positively affects the piezoelectric type PVDF, achieving to establish that from room temperature to a temperature that oscillates between 40 ° C and 50 ° C, the electrical energy stored in the condenser is increasing, which makes infer that it is thanks to the pyroelectric properties that these possess that it is possible to reduce up to 30% of its temperatures higher than those mentioned. Unlike the previous ones, in the PZT it was possible to establish that the increase in the temperature negatively affects the generation of electrical energy in the device, containing consequently that at a temperature of 20 ° C, it is possible to store the greatest amount of electric energy in the condenser, under this first, it is possible to determine that at high temperatures the piezoelectric loses up to 30% its capacity of electric power generation.
