Abstract: The present embodiments relate generally to a soft system for producing a giant magnetoelastic effect. In some embodiments, the soft system is composed of platinum-catalyzed silicone polymer matrix and neodymium-iron-boron nanomagnets. The soft system shows up to four times more enhancement of the magnetomechanical coupling factor (T/Pa) than traditional rigid counterparts owing to a distinct physical mechanism. In embodiments, the giant magnetoelastic effect is coupled with magnetic induction to implement a soft magnetoelastic generator (MEG) as an approach to biomechanical energy conversion, a technology that was heretofore conventionally challenged by low current, high internal impedance, and low water/humidity resistance for decent operation stability. This new method of biomechanical-to-electrical conversion is intrinsically waterproof since the magnetic fields are able to penetrate water with negligible intensity loss.
