Mixing a small amount of graphene into the child’s toy “Silly Putty” results in a material that can be used as a stress sensor that is significantly more sensitive that today’s typical stress measuring devices. According to this piece, “It’s so sensitive that a piece of putty pressed against the carotid artery can detect not only the heart rate, but the blood pressure of a person. It can be made hundreds of times more sensitive than a traditional strain sensor, something the researchers demonstrated by detecting the footsteps of spiders walking over it.” MORE WITH VIDEO
