Multi‐Domain Energy Harvesting with Mode‐Dependent Magneto‐Mechano‐Electric Coupling

ABSTRACT Magnetic field energy harvesting based on the magneto‐mechano‐electric (MME) principle offers a promising approach for realizing self‐powered Internet of Things systems. However, the magnetic fields in daily environments are stray and weak (<0.1 mT), greatly limiting the output power and practicality of conventional MME harvesters. Given the frequent coexistence of distinct‐frequency magnetic field and vibration excitations in real‐world scenarios, there is an urgent need for a compact and designable dual‐mode harvester to unlock performance limits. Here, we present a mode‐split MME harvester that leverages the first symmetric and second antisymmetric bending modes to most efficiently capture…
