Potentiality of magnetoelectric composites for Wireless Power Transmission in medical implants

Electric power can be wirelessly transferred to power supply medical devices, in order to reduce the size of the implants and increase their lifetime. The inductive power transmission, through the interaction between two coils, is compared to a novel magnetoelectric (ME) technology. In this case, the external coil delivers the energy to a ME receiver, made with an electroactive (e.g piezoelectric) material, bonded between two magnetostrictive layers. This new technology can overpass the issues of directionality and heating, present in the inductive transmission technique, and open new prospective for battery-less medical implants.
