| Abstract [eng] |
During usage, storage, and transportation, electronic products often become affected by a few unwanted adverse effects of the surrounding environment that compromise their working performance, reliability, and device life. There is evidence that environmental effects cause 52% of such electronic devices to fail. A vibrational piezoelectric energy harvesting system is presented in this study. The purpose of the harvester is to convert enough energy to power the deployed wireless sensors, which are becoming a huge tool in the Internet of Things market. Therefore, a study is conducted to investigate the effect of temperature [-20 ℃; 50 ℃] on the energy generation capacity of a piezoelectric energy harvester cantilever having a power density of 3.77μW/g/〖mm〗^3at room temperature. Temperature tests are performed experimentally on four similar prototypes of energy harvesters and compared with simulated results. For structural damping in finite element modes, Rayleigh damping coefficients are used to construct an accurate numerical model in COMSOL Multiphysics software. The material properties of the cantilevers, such as density and elasticity, are temperature dependent. Both these effects are suspected to influence the resonance frequency and output voltage. The findings discussed could be useful in designing PVDF-based devices for use in different climatic environments, to anticipate the maximum safe operating temperature range and the service life of the energy harvester. Such an analysis informs one about the storage conditions, and suitable final applications, and this also leads to more efficient use of existing materials and fewer device failures. |
