Graphene DeviceArborsense, Inc. is a technology startup spun out of the labs of University of Michigan Ann Arbor in 2015 with a vision to become the dominant player in wearable healthcare device market by providing each individual his/her personal health companion. At present, most, if not all, wearables in the market measure only a few physical parameters but neglect the rich chemical information available close to the human skin. We exploit the unique properties of Graphene to build rapid and sensitive transdermal biochemical vapor sensors for continuous real-time non-invasive detection of biochemical markers. Graphene is a one-atom thick carbon nanomaterial with remarkable electronic, optical, and mechanical properties which provide high sensitivity, fast response, body-pliability, and a discreet structure. This makes graphene an ideal platform to monitor clinically relevant vapor biomarkers transpiring through the skin.
