Researchers suggest a new graphene based bio-sensor that can be used to detect bacteria and wirelessly transfer data. An example use case is putting it on tooth enamel. The graphene sensor is printed on water-soluble silk and can be "bio-transferred" on organic materials The silk is then dissolved in water and the sensor remains in place.
The device also includes an RFID tag, and is powered by tiny electric charges in the bacterial cell membranes.
