Abstract

For many years, we have been developing flexible sensors made of braided piezoelectric poly-l-lactic acid (PLLA) fibers that can be tied and untied for practical applications in society. To ensure good quality of sleep, the occurrence of bruxism has been attracting attention in recent years. Currently, there is a need for a system that can easily and accurately measure the frequency of bruxism at home. Therefore, taking advantage of the braided piezoelectric PLLA cord sensor's unique characteristic of being sewable, we aimed to provide a system that can measure the frequency of bruxism using the braided piezoelectric PLLA cord sensor simply sewn onto a bed sheet on which the subject lies down. After many tests using trial and error, the sheet sensor was completed with zigzag stitching. Twenty subjects slept overnight in a hospital room on sheets integrated with a braided piezoelectric PLLA cord. Polysomnography (PSG) was simultaneously performed on these subjects. The results showed that their bruxism could be detected with an accuracy of more than 95% compared with PSG measurements, which can only be performed in a hospital by a physician and are more burdensome for the subjects, with the subjects simply lying on the bed sheet with a braided piezoelectric PLLA cord sensor sewn into it.

摘要

多年来，我们一直在研发由编织压电聚左旋乳酸（PLLA）纤维制成的柔性传感器，这种传感器可系上和解开，以便在社会实际应用中使用。为确保良好的睡眠质量，磨牙症的发生近年来一直备受关注。目前，需要一种能够在家中轻松、准确地测量磨牙症频率的系统。因此，利用编织压电PLLA线传感器可缝制的独特特性，我们旨在提供一种系统，该系统可以使用简单地缝在受试者躺卧的床单上的编织压电PLLA线传感器来测量磨牙症的频率。经过多次反复试验测试，通过曲折缝合法完成了床单传感器。20名受试者在医院病房的集成了编织压电PLLA线的床单上睡了一夜。同时对这些受试者进行了多导睡眠图（PSG）监测。结果表明，与只能由医生在医院进行且对受试者负担更大的PSG测量相比，使用缝有编织压电PLLA线传感器的床单，能够以超过95%的准确率检测出他们的磨牙症。
