Dilatant Compound 3179 + Graphine = Hypersensitive pressure detector

Dilatant Compound 3179 (previously), better known to kids young and old as Silly Putty, may finally have a proper scientific use (besides the other semi-proper uses). Add graphene to the polymer, you get a very sensitive electro-mechanical sensor that can measure breathing, pulse and even blood pressure when placed on a person's neck or chest, and even detect the footsteps of small spiders (via NPR; abstract, paywalled article on Science Mag: Sensitive electromechanical sensors using viscoelastic graphene-polymer nanocomposites).
