A new sensor, which can detect airborne chemicals either exhaled or released through the skin, would likely be the first wearable to pick up a broad array of chemical, rather than physical, attributes. U-M researchers are working with the National Science Foundation's Innovation Corps program to move the device from the lab to the marketplace.

Girish Kulkarni, Electrical Engineering Ph.D. Student, runs an experiment testing the vapor sensors that he has helped develop as part of a collaboration between Xudong Fan, BME Professor, and Zhaohui Zhong, EECS Professor, in the LBME Building on August 1, 2014. The sensors allow for the measuring of different vapors, whereas other sensors can only read for one type of vapor. (Credit: Joseph Xu, Michigan Engineering Communications & Marketing)

These nanoelectronic graphene vapor sensors can be completely embedded in a microgas chromatography system, which is the gold standard for vapor analysis, the researchers say. The entire microgas chromatography system can be integrated on a single chip with low power operation, and embedded in a badge-sized device that can be worn on the body to provide noninvasive and continuous monitoring of specific health conditions.
