Summary Mouthguard-like devices are a perfect example of the challenges of integrating sensing and electronics within a wearable device. They present a unique, potential capability for sensing of biomarkers in saliva, yielding complex and continuous information about the well-being of the wearer. There are mouthguard monitoring devices in the market but these focus mainly on impact-related injury in sports.   Description University researchers have developed mouth-based devices which function as sensors and/or biofuel cells. In one embodiment, a wearable saliva metabolite biosensor comprises a printable enzyme electrode integrated into a mouthguard. Said mouthguard enzymatic-biosensor exhibits high sensitivity, selectivity and stability using whole human saliva samples, is non-invasive and able to provide useful real-time information regarding a wearer’s health, performance and stress level. Applications include biomedical and fitness monitoring and biofuel cells for powering wearable/portable devices.
