Wearable sensor detects chemical disease markers

University of Michigan professors Sherman Fan and Zhaohui Zhong‘s newly developed graphene-based wearable sensor detects airborne chemicals that serve as disease indicators.   This could be the first wearable that monitors a broad array of chemical, rather than physical attributes. The sensor could detect acetone, a biomarker for diabetes, or abnormal levels of nitric oxide and oxygen, indicators of high blood pressure, anemia, or lung disease.
