A recent New Atlas article discussed a new wearable device that uses sweat to assess the wearer’s health. The experimental device, developed at North Carolina State University, resembles a wristwatch and features sweat-sensing technology that measures metabolites in perspiration. It tracks a person’s body chemistry in real-time in an effort to identify health problems quickly.
On the underside of the wristband is a replaceable strip that rests against the wearer’s skin. Chemical sensors in the strip gather data and relay it to hardware within that processes the data and sends the information to a paired smartphone. Currently, the device measures glucose, lactate, pH and temperature, but the team believes the functionality will expand with time.
