Demonstration of MouthIO: Customizable Oral User Interfaces with Integrated Sensing and Actuation

MouthIO is the first customizable intraoral user interface that can be equipped with various sensors and output components. It consists of an SLA-printed brace that houses a flexible PCB within a bite-proof enclosure positioned between the molar teeth and inner cheeks. All parts in contact with the oral cavity are made of bio-compatible materials to ensure safety, while the design takes into account both comfort and portability. We demonstrate MouthIO through three application examples ranging from beverage consumption monitoring, health monitoring, to assistive technology.
