Sweaty wearables

When it comes to wearables, body heat isn’t the only human by-product that scientists are interested in. Researchers at North Carolina State University have developed a wearable prototype that uses your sweat to provide an overall picture of your health.

Using a replaceable test strip embedded with chemical sensors, the device can measure the amounts of certain metabolites present in your sweat to analyse your body’s glucose, lactate, pH, and temperature levels. One day, that could tip off your doc to underlying health conditions.

‘We’re optimistic that this hardware could enable new technologies to reduce casualties during military or athletic training, by spotting health problems before they become critical,’ says Michael Daniele, an assistant professor of electrical and computer engineering at NC State who was involved in the work.
