Engineers routinely inspect bridges and other structures for cracks and corrosion. But because they can't always be there in person, one highly intelligent bridge knows what to do when trouble arises: send them an e-mail.
Dr. Jennifer A Rice, an assistant professor of civil and environmental engineering at Texas Tech in Lubbock, worked on the Jindo project when she was a doctoral student under Dr. Spencer. She and her group devised much of the software that conserves power on the network. Instead of having the radios constantly beaming information and using power, the software wakes up sensors for a few minutes so they can collect and analyze data, then switches on the radio to transmit it.
