Blink-Sensing Glasses: A Flexible Iontronic Sensing Wearable for Continuous Blink Monitoring
Highlights
- Blink-sensing glasses can capture blink patterns with clinical-grade high accuracy
- A FITS sensor is applied to monitor the blink by detecting the muscle movement
- Blink-sensing glasses can be of potential use to prognose the dry eye
- The glasses are a continuous detection manner with immunity to ambient lights
Summary
Blink reflex has long been considered closely related to physiological states, from which abundant information on ocular health and activities can be revealed. In this study, a smart glasses wearable has been developed, incorporating a flexible and sensitive pressure sensor, to monitor blink patterns by continuously detecting ocular muscular movements, referred to as blink-sensing glasses. By applying the emerging flexible iontronic sensing (FITS) sensor with the sensitivity of 340 pF/mmHg, the skin pressure variations induced by movements of the orbicularis oculi muscles can be monitored in real time. The blink-sensing glasses can successfully capture blink patterns with a high accuracy of 96.3% and have been used to differentiate the blink features from both dry-eye subjects and healthy controls. This device can be potentially used as a new clinical and research monitoring tool for continuous eye blink analysis, while providing patients with high comfortableness in long-term ambulatory and home settings.
