Put aside the Calvin Kleins, there’s a new underwear label that’s about to grab a lot of attention. Researchers from Taiwan and U.C. San Diego have devised a way to print electrochemical sensors directly onto fabric, able to monitor the body chemistry of a wearer non-invasively. Give all for the clothing wear and tear that comes with daily routine, the bio-sensors have been carefully developed to withstand any stretching, flexing and crushing arriving from its user — all without damaging the embedded mechanisms. Completely wearable and nearly undetectable, these sensors are anticipated to become the next big thing in gauging vitals, holding considerable promise for use in health, military and athletic applications.
