The MouthIO device, developed by researchers at MIT and Aarhus University, is a cutting-edge wearable resembling a dental retainer. Equipped with sensors and feedback components, it can be installed in the mouth to monitor health data and track in-mouth interactions.

Key features of MouthIO include monitoring dental habits like teeth grinding and detecting drink temperatures to prevent burns. With sensors such as accelerometers and temperature detectors, it collects data for potential health insights and improvements.

One of MouthIO’s primary goals is to assist individuals with mobility impairments. By using tongue-tap gestures, it enables users to control devices like phones and computers hands-free, allowing seamless browsing and other interactions.

MouthIO is simple and cost-effective to produce, utilizing digital modeling in Blender and 3D printing. The “open-bite” design allows users to speak naturally without a lisp, making it more comfortable for extended use.

The research team aims to further enhance the MouthIO design with more long-term studies, exploring features like wireless charging to optimize it for everyday use and accessibility.
