Sometimes the best innovations come when we overlook things we use the same way for years and years – in this case, tighty-whiteys. There’s nothing quite like a crisp, clean pair of innovative underwear. Scientists at UC San Diego have invented sweat monitoring underwear. Apparently, the sweat in your waist region holds far more chemicals that can measure bodily functions and needs. Funded by the US Office of Naval Research, the hope is that these undies will one day be able to monitor a soldier’s sweat for warning signs and automatically trigger appropriate medicinal doses. But, first, they need to stand up to the detergent tests.
