Abstract

A new class of soft energy harvesters, known as magnetoelastic generators (MEGs), has been made possible by the giant magnetoelastic effect. These generators can efficiently convert low-frequency and irregular mechanical stimuli into electricity. This review summarises the mechanism of magnetoelastic coupling and recent progress in soft magnetic composites, flexible architectures, and bio-inspired designs. We focus on the application of MEGs in some specific fields, such as wearable electronics, self-powered sensing, acoustic energy harvesting, and blue energy systems, demonstrating their unique advantages over traditional harvesters. Despite the rapid advances, there are still some challenges remain in improving energy density, such as how to improve energy density, maintain long-term stability, realize large-scale manufacturing, and do a good job in system-level power management. Finally, we point out the important opportunities and future directions, hoping to help develop and integrate the next generation magnetoelastic energy system.
