Brain activity can be monitored with tiny flexible electronics which could roll up to fit in a pocket. Charles Lieber, a nanoscientist and nanotechnologist at Harvard University, has designed latest ultra-thin electronics flexible enough to get stuffed into the needle of a syringe with a diameter as small as the average width of a human hair. Traditional electronics are rigid and the procedures to measure brain activity would involve surgery; surgeons would make an opening equal to the siz...
