In this work, a novel barium titanate–coated cobalt ferrite core–shell magnetoelectric nanoparticle and poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate–based wearable energy‐harvesting patch for wireless power‐transfer applications are proposed. The developed flexible patch has unique ease of fabrication and high‐efficiency energy conversion capability from the magnetic field and mechanical motion to the electric field as compared to bulk or thin‐film‐based devices. This unique power‐transfer capability of this device is achieved due to the crystalline nature of fabricated nanoparticles, which is confirmed using X‐ray diffraction and high‐resolution transmission electron microscopy. This wearable patch can generate a high voltage of 560 mV when exposed to a 40 μT alternating magnetic field at the resonance frequency of 48.6 kHz. The hybrid mode of electric power generation is achieved by coupling bodily motion with the remotely applied alternating magnetic field (40 μT), which results in the generation of a higher electric potential of 860 mV and maximum power density of 0.458 mW cm−3 across a 10 kΩ load. The maximum magnetoelectric coefficient is recorded as 1300 mV cm−1 Oe−1. The flexible nature and hybrid operation of the proposed device make it an efficient alternative for powering a wide range of wearable medical electronic devices.

Multiferroic materials have become the new era of research because it exhibits the presence of more than two ferroic orderings in its same phase. The pure copper ferrite nano powders have been prepared using sol-gel auto combustion method. The particle size is found to be near about 30-40 nm. Pure copper ferrite nanoparticles have been chosen to prepare because of its improved dielectric and structural properties. The sharpened peaks obtained from the XRD diffraction pattern confirms the crystalline nature of the sample. The structural and impedance studies of pure copper ferrites has also been reported. The SEM analysis confirms the formation of nanoparticles by revealing the value of grain size in nanometer range. The dielectric studies exhibit the Maxwell Wagner polarization and impedance spectroscopy confirms the contribution in conductivity from both grains and grain boundaries at room temperature. The fabrication of hydroelectric cell having area=0.75 cm2 has been done using pure copper ferrite nanoparticles which have shown improved value of current in wet state as compared to other ferrites like cobalt ferrites and bismuth ferrites. These all properties are responsible for improving the structural stability and thus this material can be suggested for fabricating the hydroelectric cells.
