本文旨在研制一种基于柔性聚合物传感器的手指关节角度测量系统。在康复中，定量评估人体运动对有效治疗是很重要的。在本研究中，我们重点研究手的抓握动作，这是进食和饮水的重要动作。关于柔性聚合物传感器，在以往的研究中，已经阐明了柔性聚合物传感器的输出与测量表面的平均曲率成正比。因此，使用该传感器，可以通过将传感器附着在手指表面来测量手指的弯曲运动。首先，从理论上研究了手指表面平均曲率与手指关节角度的关系。然后，为了得到传感器输出与手指关节角度之间的关系，测量了抓取亚克力气缸时传感器输出与手指关节角度之间的关系。实验结果表明，所开发的系统可用于手指关节角度的测量。
This paper aims to develop a measurement system for the finger joint angle by using a flexible polymer sensor. In rehabilitation, it is important to evaluate human motions quantitatively for effective treatment. In this study, we focus on hand's grasping motion, which is important motion for eating and drinking. About the flexible polymer sensor, in the previous studies, it has been elucidated that the outputs from the flexible polymer sensor are proportional to the average curvature of measuring surface. Therefore, using the sensor, finger bending motion can be measured by attaching the sensor on finger surface. Firstly, the relationship between the average curvature of finger surface and finger joint angle is theoretically investigated. Then, in order to obtain the relationship between sensor outputs and finger joint angles, sensor outputs and finger joint angles during grasping acrylic cylinders are measured. From the results, it was found that the developed system is useful to measure the finger joint angles.
