Year: 2024
Type: article
Abstract: Magnetoelectric composite-based wireless energy transfer (WET) comprising omnidirectional ring-shaped transmitter and laminated plate receiver elements have been studied experimentally and theoretically. The objective is to reveal the conditions conducive to achieving optimal power based on the device geometries, the relative orientations, and the operating conditions, including the vibrational frequency, applied electric field, bias magnetic field, and the corresponding resistive load. The reformulated physics-based model establishes the dependence of the output power on the load resistance, elucidating a strong interrelationship between the transferred power, vibrational displacement, and strain transduction coefficient based on relaxing all previous simplifying assumptions. The model ascertained the non-monotonic variation of the output power as a function of the interface coupling factor, emphasizing the crucial influence of gradual change in material properties within the strain-mediated magnetoelectric transmitter and receiver devices, i.e., an agile design framework for multiferroics-based power transfer devices.
