We link low-power sensors together for applications in energy and the environment. Such networks combine microfabricated and off-the-shelf parts. Small wireless radios enable high-density sampling at lower cost than ever before, leading to both water quality improvement and greater understanding of fundamental environmental processes such as sediment transport.
This project bridges the size spectrum from nanoscale engineered sensor materials, to microscale data-conversion components on a circuit board, to global transmission of environmental data over the internet. See this IEEE Spectrum slideshow and podcast for more on these projects in the Ohio River area.
