The Cymanus is a novel flex sensor glove for measuring hand kinematics in primates. It was used to monitor 9 joints of a rhesus macaque performing a grasping task with 25 objects. Over 6 days, the monkey tolerated the glove and showed no significant impairment in performance. The sensors linearly tracked joint angles, with joint trajectories preserved over days. Angular positions discriminated objects as accurately as electromyograms recorded simultaneously from 24 arm and hand muscles, and were maximally informative of object identity at the end of reach-to-grasp. In a further validation of the glove, muscle activity controlling a joint was correlated with the joint's angular acceleration 70 ms later.
Cymanus 是一种新型的柔性传感器手套，用于测量灵长类动物手部运动学。它被用于监测一只猕猴用 25 个物体完成抓握任务时的 9 个关节。在 6 天的时间里，猴子耐受了手套，且在表现上没有出现显著的损伤。传感器线性地跟踪关节角度，关节轨迹可以保持多天。在伸手抓握的末端，关节位置能像同时记录的来自 24 个手臂和手部肌肉的肌电图一样准确地识别物体，且对物体身份的信息提供达到最大。在对手套的进一步验证中，控制一个关节的肌肉活动与 70 毫秒后的关节角加速度相关。
