Smart materials such as piezoelectrics, multiferroics, magnetoelectrics, triboelectrics, thermoelectrics, pyroelectrics, and photovoltaics transduce energy from one form to another. Energy harvesting technology using such smart materials promotes the development of self-powered electronics systems through an effective conversion of otherwise wasted ambient energy in the environment into useful electrical energy. This symposium will address up-to-date developments in smart materials and practical applications with special emphasis on energy generation and storage for self-powered electronics. In particular, the symposium addresses current challenges and strategies in developing prospective energy generation and storage materials and systems. This symposium will serve as a platform, not only to share novel ideas and recent research experiences, but to establish fruitful potential collaborations among material scientists and device engineers in various fields of smart materials and energy technologies.
As an example of the new sources of energy, mechanical vibrations and low amplitude magnetic fields are freely available in our surroundings on a 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 a magneto-mechano-electric (MME) generator have shown a 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.
