Among the muscles in the body, the ones in the tongue are probably the most overlooked. You don't go to the gym to work out your tongue. (Please do not tell me about your tongue workouts, kaithx.) Still, it's strong and dexterous. That's why engineers are looking into making tongue-controlled wheelchairs for people who aren't able to steer themselves with their hands or arms. A tongue-driven electric wheelchair could be an alternative to sip-and-puff wheelchairs, which users control using their breath.
Bracelets or belts that track your activity and vitals may soon be a thing of the past. Engineers from the University of Illinois at Urbana-Champaign and Northwestern University have produced a health-monitoring device that looks like a Band-Aid. The thin, soft patch can stick to and move with the skin, all while wirelessly sending vital updates to your designated cellphone or computer.
