A new kind of computer circuit printed on ultrathin rubber would make the perfect "brain wrapper," says its inventor. Usually computer circuits are etched on rigid, plastic boards, but University of Illinois researcher John Rogers has successfully placed circuits on a rubbery material that can bend and stretch. Many groups have been working on developing this technology, but Rogers is the first to demonstrate that his bendy circuits actually work. Rogers says the circuits could wrap around part or all of the brain, to monitor its electrical activity. Or — in future applications — to interface with your brain, perhaps using antennae to establish a wireless neural link to the internet so you can be Googling with your mind.
