Development of wearable scratching monitoring system

为了评价皮肤病的瘙痒感觉和治疗过程，本工作开发了人体抓挠行为监测系统。为此，设计了指甲式划痕声传感器、手指弯曲聚合物传感器和环式指力传感器，并通过实验验证了其抗划痕监测的有效性。此外，还研究了刮擦声传感器输出与剪切力、速度等刮擦运动特性之间的关系。并构建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.
