Project Description
Asleep is an intelligent patch for obstructive sleep apnea (OSA) patients. Compared with traditional treatment like continuous positive airway pressure, it greatly improving the comfort. The EMG module attached to the jaw timely stimulates the genioglossus muscle, ensuring an unobstructed airway during sleep. The neck-side sensor monitors heart rate and blood oxygen, issuing alerts for life-threatening respiratory pauses. Users can view sleep quality reports and adjust program settings via the app.
Production
Made by flexible fabric and replaceable medical hydrogel tape, the patch integrates stretchable circuits in the interlayer to connect three modules in rubber bases. The shell is made by polycarbonate plastic and house electronic components. The electrodes of EMG module stimulate genioglossus muscle, while PPG module assess heart rate and pulse oximetry. Battery module guarantees uninterrupted power throughout sleep. Bluetooth links modules to a mobile application.
Interaction
The EMG module centered on the mandible, and two neck side modules covering the carotid artery constitute this compact wearable. The patch affixed along the jawbone, fits various sizes due to its stretchable pattern. This smart patch monitors physiological parameters, generating sleep reports via the app. In the event of breathing pauses, the EMG module stimulates the genioglossal muscle. Prolonged life-threatening pauses trigger vibrations and alarms to awaken the user and alert those nearby.
