S1: Piezoelectric and Mechano-Magneto-Electric Energy Harvesting

Mechanical vibrations and low amplitude magnetic field are freely available in our surroundings on variety of platforms. Conversion of these mechanical and magnetic fields into electricity with high efficiency can provide ubiquitous energy sources. For example – we are surrounded with 50/60 Hz parasitic magnetic noise arising from power delivery infrastructure. Recent investigations on magneto-mechano-electric (MME) generator have shown possibility to capture this magnetic field with high power density. This MME generator can be a ubiquitous power source for wireless sensor networks, low power electric devices, and wireless charging systems. Multiferroic magnetoelectric (ME) composites are attractive materials for design of MME generators and dual-phase harvesters. This symposium will review the fundamental physics, fabrication processes, modeling methods and device design for ME composite material systems with respect to MME generator application.
