Clean? This Wristband Knows

Millions of people get infections from hospital care each year in the U.S. Many cases arise from improper hand hygiene among hospital workers. A startup called IntelligentM wants to make hospitals healthier by encouraging workers to clean their hands properly. Its solution is a bracelet that vibrates when the wearer has scrubbed sufficiently, giving employees a way to check their habits and letting employers know who is and isn’t doing things right.
