针对人体复杂运动的传感问题，我们研制了一种由压电聚L-乳酸（PLLA）纤维组装而成的新型柔性纤维传感器（PLLA纤维传感器）。作为本研究的早期阶段，我们尝试使用PLLA光纤传感器检测脉搏率并观察人手臂的运动。首先，我们制备左手和右手螺旋扭转线圈（PLLA纤维左手和右手线圈），其通过以10的拉伸比拉伸PLLA纤维而形成。结果发现，PLLA光纤传感器可以非常高的精度测量脉搏率。同时，我们能够使用PLLA光纤传感器检测前臂和上臂的旋转。
Toward sensing the complicated motion of the human body, we have developed a new soft and flexible fiber sensor assembled from piezoelectric poly-L-lactic acid (PLLA) fibers (PLLA fiber sensor). As an early stage of this study, we attempted to detect the pulse rate and observe the motion of a human arm using the PLLA fiber sensor. First, we prepared left-hand and right-hand helical torsion coils (PLLA fiber left-hand and right-hand coils), which were formed by drawing a PLLA fiber with a drawing ratio of ten. As a result, we found that the pulse rate could be measured with extremely high accuracy by the PLLA fiber sensor. At the same time, we were able to detect the rotation of the forearm and upper arm using PLLA fiber sensors.
