Autonomous energy-scavenging micro devices will test water quality, monitor bridges, more

Researchers are using photonics in their quest to "bring the lab to the sample," developing sophisticated micro instruments that scavenge power from sunlight, body heat, or other sources, for uses such as monitoring water quality or assessing bridge safety.
