Sažetak
Converting vibration energy into electric energy via the piezoelectric effect is one of the most prominent small-scale energy scaveng¬ing concepts aimed at powering ubiquitous wireless sensor networks. Several analytical and numerical models, which have also been experimentally validated, have been proposed in literature to characterise the behaviour of cantilever vibration energy scavengers. A finite element coupled electromechanical model of a harmonically excited multilayer energy scavenging device is developed and investigated in this work by using the ANSYS® software. The intricate design of the device is based on off-the-shelf Midé Technology® Volture energy scavengers. The results of the modal and harmonic FEM analyses are experimentally validated via a suitable set-up employing two types of cantilevers as well as several tip masses and electrical resistances. It could hence be proven that numerical analysis is a reliable tool for predicting maximum available power outputs in the presence of electromechanical coupling effects.
