Wearable sensors that monitor physical activity are hardly anything new, but some researchers from MSU's Department of Kinesiology are taking the idea quite a bit farther with their latest project. They've developed a new system that employs a network of sensors that not only track movement, but can monitor things like tilt, posture and the proximity of limbs to each other. That, the researchers say, allows them to detect different types of activity, and more accurately measure the energy ex... pended on them. Of course, it is still just a prototype, but it'll apparently soon be put to the test by some graduate students, and there's plenty of backing behind it -- the project is being funded two-year, $411,000 grant from the National Institutes of Health.
