Individuals who have limited hand function can control devices such as smartphones, computers, and wheelchairs by wearing a smart mouthguard. The novel bite-controlled optoelectronic system contains integrated pressure sensors to detect occlusal patterns. These patterns are translated into data inputs with 98 percent accuracy.
The research team first designed a sensor comprising a series of contact pads containing different colored phosphors, which emit light in response to pressure. The array of contact pads is placed within a flexible mouthguard.
Biting causes the contact pads to mechanically deform and emit light in different colors and intensities, which can be measured and processed using machine learning algorithms. The data collected can be used for highly accuracy remote control and operation of various electronic devices.
