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.
眨眼反射长期以来一直被认为与生理状态密切相关，从中可以揭示出有关眼部健康和活动的丰富信息。在本研究中，已开发出一种智能眼镜可穿戴设备，它集成了一个灵活且灵敏的压力传感器，通过持续检测眼部肌肉运动来监测眨眼模式，即眨眼感应眼镜。通过应用灵敏度为340 pF/mmHg的新型柔性离子传感（FITS）传感器，可以实时监测眼轮匝肌运动引起的皮肤压力变化。眨眼感应眼镜能够以96.3%的高精度成功捕捉眨眼模式，并已用于区分干眼受试者和健康对照的眨眼特征。该设备有可能用作一种新的临床和研究监测工具，用于持续的眨眼分析，同时在长期动态和家庭环境中为患者提供高度的舒适度。
