| Abstract Scope |
Advances in wireless sensor technologies have resulted in increased demand for on-board energy harvesting devices that convert ambient energy into electricity. In this research, we focus on harvesting mechanical vibrations using piezoelectric effect using high energy density functional piezoelectric material 0.8 [Pb (Zr0.52Ti0.48)O3]–0.2 [Pb (Zn1/3 Nb2/3)O3] (PZT-PZN). A simple piezoelectric rectangular bimorph transducer was designed and simulated for frequency-based analysis using COMSOL Multiphysics software. Next, various geometrical shapes such as a trapezoid and two-piece trapezoid were designed to achieve broadband energy harvesting response. The new geometry was tuned to specific frequency range (10 – 30 Hz) that is found in most engineering applications. Results indicate that piezoelectric bimorph energy harvesters can achieve a high-power density of 15–16 mW/cm³ at a relatively low operating frequency range of 19–22 Hz. This research could lead to significant advancements in the design and fabrication of broadband vibration energy harvesting devices and systems. |
