Graphene ‘camera’ captures real-time electrical activity of beating heart: Graphene sheet acts like video camera to record fleeting electrical signals of neurons, cardiac cells

Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image -- almost like a video camera -- of the faint electric fields generated by the rhythmic firing of the heart's muscle cells. The graphene camera represents a new type of sensor useful…
