New Wearable 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.


“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 PhD 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.” For further information see the IDTechEx report on Electronic Skin Patches 2020-2030.


“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.


Why vitamin C is important

Vitamin C is an essential dietary component, as it cannot be synthesized by the human body and must be obtained through our food or via vitamin supplements. The vitamin is important for supporting immune health and collagen production, a vital player in wound healing, as well as improving iron absorption from plant-based foods. Ongoing research is examining whether or not the vitamin’s role as an antioxidant might support its use in treating diseases like cancer and heart disease.
