My latest article for TheFeature is about the future of wireless sensors that can be implanted into your body, enabling your cell phone to act as a doctor in your pocket.
The human body is like a car. Take care of it, and it might even last a lifetime. If it has problems you may have to bring it to the mechanic, your doctor. Once you're there, though, the knocks and pings always seem to disappear, leaving you with a lot of explaining to do. Ideally, for treatment's sake anyway, your physician would follow you around and do an instant examination at the moment a symptom rears its ugly head. That's the idea behind UbiMon, a wireless sensor network of medical-monitoring devices that will eventually be implanted right into the body.
