A mouthguard is being developed to continuously monitor lactate, glucose or other analytes, an advance that could help athletes optimise their performances. mouthguard Modified mouthguard monitors levels of lactate (Credit: NextFlex) Lactate is an important marker of fitness and fatigue and by enabling continuous monitoring during training and sports the mouthguard system is expected to give athletes and their coaches unique access to key performance information for real-time optimisation. The wirelessly rechargeable electrochemical sensor - which uses Bluetooth Low Energy for data communication - is fabricated on a flexible plastic foil, then mounted on the mouthguard. The mouthguard system is being developed by PARC, a subsidiary of Xerox Corporation, and the University of California San Diego. It has received funding from NextFlex, a consortium of public and private entities formed to advance the development of flexible-hybrid electronics (FHE).
