"Multimodal Energy Harvesting"
(Seminar/Conference)
SEMINAR by Shashank Priya / Virginia Tech
NOTE THE LOCATION CHANGE from campus to the Corporate Research Center!
The vast reduction in size and power consumption of sensors and CMOS circuitry has led to focused research effort on the power sources which can replace the batteries or enhance their lifetime. The concern with batteries has been that they must always be charged before use. In several applications the operation of externally recharging or battery replacement can be tedious and expensive and may even be prohibited by the infrastructure or location. Logically, the emphasis is on developing miniature cost-effective systems that can transform locally available energy sources to electrical energy. The choice for environmental energy sources are several including vibrations, light, temperature gradient, wind, acoustics, magnetic currents, water currents, and human activity. The selection of the energy source and converter is case dependent. This presentation reports the progress made in our research on developing energy harvesting modules for platforms that are rich in vibrations, magnetic field and wind emphasizing wireless sensor networks and fabrication of self-powered chips. This talk will also introduce the activities planned for recently launched Center for Energy Harvesting Materials and Systems.
