With aging, disability of the body can easily occur because the function of the body is degraded. Especially, swallowing disorder is regarded as a crucial issue because patients cannot obtain the nutrients from food by swallowing it. Hence, the rehabilitation of swallowing disorder is urgently required. However, the conventional device for swallowing rehabilitation has shown some limitations due to its external power source and internal circuit. Herein, a self-powered triboelectric nanogenerator for swallowing rehabilitation (TSR) is proposed. To increase the electrical output and pressure sensitivity of the TSR, the tilted reactive ion etching is conducted and the electrical output and pressure sensitivity are increased by 206% and 370%, respectively. The effect of the tilted reactive ion etching into the electrical output generated from the TSR is systematically analyzed. When the tongue is pressing, licking, and holding the TSR, each motion is successfully detected through the proposed TSR. Based on these results, the smart swallowing rehabilitation monitoring system (SSRMS) is implemented as the application and the SSRMS could successfully detect the pressing by the tongue. Considering these results, the SSRMS can be expected to be utilized as a promising smart swallowing rehabilitation monitoring system in near future.
随着年龄的增长，身体功能退化，身体残疾很容易发生。特别是吞咽障碍被视为一个关键问题，因为患者无法通过吞咽食物获取营养。因此，迫切需要对吞咽障碍进行康复治疗。然而，传统的吞咽康复设备由于其外部电源和内部电路存在一些局限性。在此，提出了一种用于吞咽康复的自供电摩擦纳米发电机（TSR）。为了提高TSR的电输出和压力灵敏度，进行了倾斜反应离子蚀刻，电输出和压力灵敏度分别提高了206%和370%。系统地分析了倾斜反应离子蚀刻对TSR产生的电输出的影响。当舌头按压、舔舐和握住TSR时，通过所提出的TSR成功检测到每个动作。基于这些结果，实现了智能吞咽康复监测系统（SSRMS）作为应用，并且SSRMS能够成功检测到舌头的按压。考虑到这些结果，预计SSRMS在不久的将来可作为一种有前景的智能吞咽康复监测系统加以利用。
