Abstract
Piezoelectric vibration energy harvesting has been receiving attention in scientific and industrial fields due to the ability to power supply sensors and devices through the direct piezoelectric effect. Since external conditions of excitation can vary through the harvesting process, there is a challenge to enhance energy harvesting capacity and adaptive systems are of special interest. This paper investigates the synergistic use of smart materials considering a piezoelectric energy harvester coupled to a shape memory alloy element with the objective to increase operational range of the energy harvester. A constitutive model with polynomial phase transformation kinetics is used to describe the SMA thermomechanical behavior. Numerical simulations are carried out to evaluate the system response under different conditions. Results show that the special characteristics of shape memory alloys allow the energy harvesting system to operate over a wide frequency range.
