- 用柔性布料+气动肌肉构造轻量触觉装置
- 实时调节触感强度，引导肘关节角度，误差小
- 适合康复训练或人机交互场景，佩戴舒适
可穿戴触觉设备需求快速增长，但多数设备妨碍活动且触觉反馈不自然。为此，本文提出一种基于轻量化可穿戴布料执行器的肘角引导系统。该执行器由织物材料制成，集成两个麦克宾型人工肌肉，极为轻便，可精准传递表面触觉刺激，直观引导肘关节屈伸。触觉感应随人体自然姿态自适应调整，不干扰用户动作。系统通过实时调节触觉强度，测量并引导肘角变化。实验验证了其有效性与准确性。
原文摘要 · Abstract (English)
The demand for wearable haptic devices has rapidly increased for various applications. However, many haptic devices interfere with the wearer's activities and movements. In addition, several haptic devices fail to elicit intuitive haptic sensations by adjusting to the natural posture of the wearer. To address these issues, we propose an elbow angle guidance system using a lightweight wearable fabric actuator. The proposed actuator is made of fabric and has two McKibben-type artificial muscles attached to it, rendering it extremely lightweight and facilitating the delivery of surface haptic sensations to intuitively induce elbow extension and flexion. The surface haptic sensation elicited by the fabric actuator is adjusted to natural body movements without interfering with the wearer's movements. Moreover, the proposed system measures and guides the elbow angle by changing the intensity of the surface haptic sensation delivered to users in real time. The accuracy of the proposed system is demonstrated through experiments involving human participants.
