Sensors made of graphene and plasticine monitor blood pressure in real time over a 24-hour period. Just add a little graphene, you can turn the plasticine into a pressure sensor. This sensor is extremely sensitive, not only to monitor the pulse of the body, and even to explore the footsteps of a small spider. This graphene plasticine is called "G-putty," and developers hope it will develop devices that continuously monitor blood pressure. In addition G-putty also showed the ability to self-repair, indicating that it may become more intelligent graphene composites. Since graphene was first isolated in 2004, researchers have attempted to add these thin layers of carbon atoms to a variety of materials in the hope of creating composites that benefit from the high strength and excellent conductivity of graphene. Surprisingly, however, few have attempted to mix graphene with such viscoelastic materials as plasticine. The plasticine exhibits both elastic solid and liquid characteristics, such as putting a plasticine on a hole that slowly leaks past. Conor Boland, a researcher at the Jonathan Coleman Nanotechnology Laboratory at Dublin's Trinity College Dublin, said he was curious what would happen if graphene was mixed with plasticine. "I'd love to say that the idea was conceived, but not," Coleman said with a smile: "Because we happen to have a tradition of using household appliances for scientific research." (His team was at In 2014, it was discovered that graphene can be obtained by rapidly stirring the graphite with a stirrer in the kitchen.)
