That’s why IntelligentM, a startup, has decided to create a bracelet that vibrates when someone has washed his hands sufficiently. Currently, people are paid to secretly monitor the hygiene habits of doctors, nurses and the like. Obviously, this technology would be cheaper and likely more efficient.
The bracelet works simply enough, by reading RFID tags at hand-washing and sanitizing stations. It then monitors how much time someone spends washing his hands. When that washing is sufficient is buzzes once. If it isn’t, it buzzes three times.
Often, the beauty is in the simplicity.
