G-putty based inks can be printed as a thin-film onto elastic substrates, including plasters, and attached easily to the skin (Image: Trinity College Dublin) The team from Trinity College Dublin have created the next generation sensing technology using so-called G-Putty, an innovation from Trinity in which putty (polysilicone, found in children’s toy ‘silly putty’) is infused with graphene, making the material’s electrical resistance extremely sensitive to slight deformations.
