Dissolvable Devices Keep Tabs on the Brain

It was a pretty big "what if." What if you could design an implantable medical device that was durable, reliable and accurate, but also dissolved into completely harmless materials when its work was done? The two concepts are a bit incompatible, but John Rogers and his team were up to the challenge of bringing them together. Rogers, a professor of materials science, engineering and bioengineering at the University of Illinois at Urbana-Champaign, designed novel electronic sensors that
