Mechanical vibrations, low amplitude magnetic fields, and low-grade thermal energy are freely available in our surroundings on variety of platforms. Conversion of this wasted energy into electricity with high efficiency can provide ubiquitous energy sources. To overcome the energy-insufficiency issue of a single energy harvesting device, hybrid energy harvesting systems have been proposed in recent years. Hybrid energy harvesting technology is not only using the energy from multiple sources, but also converting energy into electricity by multiple types of energy transduction mechanisms, such as piezoelectric, electromagnetic induction, triboelectrification, magnetoelectric coupling, pyroelectric, and thermoelectric, in single device structure.
This symposium will review the fundamental physics, fabrication processes, modeling methods, and device design for hybrid energy harvesting materials and devices.
