John Rogers and his team at the University of Illinois, Champaign-Urbana have come up with a way to monitor the body electronically that really sticks. They have developed a small, flexible circuit device that sticks comfortably to the skin and is artfully camouflaged as a temporary tattoo. It can read a patient's brainwaves, heart rate and muscle activity while they are going about their normal activity, making it possible to cut back on visits to the doctor's office. Rogers envisions one day an implantable circuit that diagnoses and perhaps treats seizures.
