New wearable sensor tracks vitamin C levels in sweat
A team at the University of California San Diego has developed a wearable, non invasive vitamin C sensor that could provide a new, highly personalized option for users to track their daily nutritional intake and dietary adherence. The study was published in the May 18, 2020 issue of ACS Sensors.
"Wearable sensors have traditionally been focused on their use in tracking physical activity, or for monitoring disease pathologies, like in diabetes," said first-author Juliane Sempionatto, a Ph.D. Candidate in nanoengineering in Joseph Wang's lab at the UC San Diego Jacobs School of Engineering. "This is the first demonstration of using an enzyme-based approach to track changes in the level of a necessary vitamin, and opens a new frontier in the wearable device arena."
"Wearable sensors have rarely been considered for precision nutrition," said Joseph Wang, a professor of nanoengineering and director of the Center of Wearable Sensors at UC San Diego.
