(a) MouthIO schematic. The oral interface consists of three components: (1) the 3D-printed brace that gets attachedto the teeth, (2) the integrated flexible PCB with circuits, battery, microcontroller, and sensors, and (3) the PCB housing towater-proof encapsulate the electronics and make it bite-save. (b) Wearing a MouthIO interface integrating two capacitivetouchpads that enable the detection of tongue tapping, serving as an assistive tool for users with motor impairment.

Project Overview
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. Our MouthIO design and fabrication technique enables makers to customize the oral user interfaces in both form and function at low cost. 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.
