RALEIGH – The device might be a cap on your tooth or a band on your wrist. Whatever it is, researchers promise the wearer won’t notice it’s there.
What they are are sensor devices that can check a range of body functions, including vitals such as heart rate and oxygen levels. And, as a bonus, they are powered by energy harvested from the body wearing them.
“You never have to change a battery,” says John Muth, an engineering professor and deputy program director at the Center for Advanced Self-Power Systems of Integrated Sensors and Technologies at N.C. State University.
