手指关节角度的精确测量在康复、仿生等领域具有重要意义。本文提出了一种基于光纤布拉格光栅（FBG）传感器的弯曲传感手套，用于手指关节角度的高精度测量。我们评估其准确性和可重复性的四个人类受试者通过测量他们的近端指间关节（PIP）的食指，中指和无名指的角度。我们的手套显示出与惯性测量单元（IMU）传感器读数的良好一致性（R平方：0.9985）。手套优于几个现有的传感器，表现出最大误差（1.42度），平均误差（0.45度）和最大标准差（0.56度）。将来，这项研究将扩展到所有关节。
Accurate measurement of finger joint angles is very important in the fields such as rehabilitation, bionics, etc. In this paper, we present a fiber Bragg grating (FBG) sensor-based flexure sensing glove to measure the finger joint angles with high accuracy. We evaluate its accuracy and repeatability on four human subjects by measuring their proximal interphalangeal (PIP) joint angles of the index, middle and the ring fingers. Our glove showed excellent agreement (R-Squared: 0.9985) with the inertial measurement unit (IMU) sensor readings. The glove outperforms several existing sensors exhibiting a maximum error (1.42 degrees), mean error (0.45 degrees) and maximum standard deviation (0.56 degrees). In the future, the study will be extended to all the joints.
