Abstract

Magnetoelectric (ME) transducers, composed of piezoelectric and magnetostrictive layers, have recently been demonstrated as a receiver in wireless power transfer (WPT) to miniature implantable medical devices (IMDs). Due to their complex mechano-magnetic-electric interactions, methods for biocompatible coating and packaging of ME transducers within a small IMD need to be investigated to achieve optimal ME response. This paper describes the effects of biocompatible coating and packaging using Polydimethylsiloxane (PDMS) on ME response. Three bar-shaped ~ 5×1×1 mm3 ME transducers were fabricated with a 508 μm thick piezoelectric layer. In air, adding ~ 35 μm of PDMS coating reduced the received power (PL) by 19.4% (131.04 μW vs. 105.62 μW). The ME transducer were mounted on a printed circuit board (PCB) and inside a custom 3D-printed holder. The PCB mounting had no significant effect on ME transducer PL, but the 3D-printed holder considerably reduced PL from 112.89 μW to 39.02 μW, when measured in a water medium.
