MouthIO introduces the first customizable intraoral user interface that combines various sensors and output components, all housed within a bio-compatible brace worn in the mouth. The device can be tailored for diverse applications:

• Health Monitoring – Tracks teeth grinding (bruxism) during sleep using an accelerometer, offering new ways to keep an eye on oral health.
• Assistive Technology – Detects tongue touches via capacitive touchpads behind the upper teeth, offering hands-free device control for individuals with motor impairments.
• Beverage Consumption Monitoring – Measures beverage temperature with a sensor and vibration feedback, helping users with oral hypoesthesia.

A user study found MouthIO to be highly wearable and socially accepted, while technical tests have confirmed its durability against adult bite forces. This project is a great example of how computer science is finding its way into unexpected places, making life better in the process.
