The device – called the “Chem-Phys patch” – measures real-time levels of lactate, a biochemical that serves as an indicator of physical activity, as well as the heart’s electrical activity.

Put simply, the novel technology monitors a person’s fitness levels and heart function at the same time, and it is the first device that can do so.

“One of the overarching goals of our research is to build a wearable tricorder-like device that can measure simultaneously a whole suite of chemical, physical and electrophysiological signals continuously throughout the day,” says co-project leader Patrick Mercier, of the Jacobs School of Engineering at the University of California-San Diego.

“This research represents an … View Original Article
