A team from the National Taiwan University in Taipei, Taiwan is developing a tiny tooth sensor to detect oral activities. The small sensor acts as an accelerometer for your teeth. Any chewing, speaking, drinking or coughing can be detected with 93.8 percent accuracy among 8 research participants using a programmed algorithm. For the study, researchers attached the sensor using dental adhesive, however, the sensor is designed to connect wirelessly via Bluetooth to a mobile device. While the sensor is currently only able to detect oral movements, future applications may extend to sports medicine, dentistry and speech therapy.
