University of Illinois professor John Rogers has made another breakthrough in flexible medical electronics. His team has created an EEG system that sticks to the skin behind one’s ear to monitor brain activity. The miniature, lightweight, gold electrode device sticks to the skin without adhesive, and can be worn continuously for 2 weeks.
While not yet precise or fast enough to replace traditional EEG, study participants were able to spell the word “computer” on a screen using their brain’s electrical activity.
Rogers is now concentrating on refining the device for medical applications, and making it wireless. In a related Neuron paper, he describes advances in soft electronic interface technologies for neuroscience research.
