Development of wearable scratching monitoring system

本研究开发了一种用于皮肤瘙痒感觉和皮肤病治疗过程监测的人体抓挠行为监测系统。为此，设计了一种安装在指甲上的刮擦声传感器、一种手指弯曲聚合物传感器和一种环形手指力传感器，并通过实验验证了其对刮擦监测的有效性。此外，从划痕声传感器的传感器输出和划痕运动特性，如剪切力和速度之间的关系进行了研究。建立了运动特性的估计方法。

In this work, monitoring system for human scratching behavior has been developed in order to evaluate itch sensation and therapeutic process of skin disease. For this purpose, a nail-mounted scratch sound sensor, a finger bending polymer sensor, and a ring-type finger force senor were designed and the effectiveness against monitoring of scratching were verified by experiment. Additionally, relationship between sensor output from scratch sound sensor and scratch motion properties such as shear force and velocity wasinvestigated. And estimation methods of motion properties were constructed.
