Introduction: : The magnetoelastic effect, also known as the Villari effect and first discovered in 1865 by the Italian experimental physicist Emilio Villari, refers to the change in a material’s magnetic field under mechanical stress. Traditionally observed in rigid metals and metal alloys with external magnetic fields, it has been largely overlooked in soft bioelectronics due to limited magnetization under physiological stress, structural complexity, and extreme modulus mismatch with human tissues. In 2021, we reported the discovery of a giant magnetoelastic effect in a soft polymer system, and subsequently in a liquid permanent fluidic magnet. This breakthrough opens a fundamentally new pathway for developing intrinsically waterproof and biocompatible soft bioelectronics for diagnostics, therapeutics, and energy applications. Our UCLA team is pioneering the use of this effect to advance personalized healthcare and sustainable energy applications.
