Sweat band

A wearable sensor that carries out chemical analysis of your sweat when exercising, for instance, and sends data about metabolites, electrolytes and skin temperature to a smart phone app, could be the next device to assist in sports and health science and perhaps offer consumers a detailed view of their body chemistry. Health monitors are big business, this latest development could open up monitoring of critical changes in hydration levels, body electrolytes and extreme temperature rises and falls. "While [the] wearable, non-invasive technology works well on sweating athletes, there are likely to be many other applications of the technology for measuring vital metabolite and electrolyte levels of healthy persons in daily life," explains Berkeley's George Brooks. "It can also be adapted to monitor other body fluids for those suffering from illness and injury."
