Arborsense, Inc. is a technology startup spun out of the labs of University of Michigan Ann Arbor focused on wearable healthcare devices. 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. The firm utilizes Graphene to build rapid and sensitive transdermal biochemical vapor sensors for continuous real-time non-invasive detection of biochemical markers. The growing need for personalized health-care is highlighted by the estimated market size of $19 billion for wearable biosensors by 2018, pointing towards the potential commercial opportunity. The firm is focused on graphene based nanoelectronic wearable sensor will be developed for real-time alcohol monitoring using the vapors transpiring through the skin.
