本文介绍了一种用于局部压力和振动触觉反馈的气动腕带--波纹带的设计和控制。该腕带有八个等间距的气动波纹管，延伸到手腕，由聚酯热塑性聚氨酯(TPU)层构成，形成了一种灵活、轻巧(11克)的腕带，能够向用户呈现复杂的压力和振动信号。每个波纹管可以承受超过100千帕，延伸超过10毫米，并在零位移下施加超过10N的力。对给定的输入压力和波纹管位移进行了准静态分析，估算了波纹管的力，并对其动态响应进行了实验研究。最后，我们演示了腕带向手腕传递各种触觉提示的能力，包括均匀挤压、均匀振动、局部力和局部振动。Bellowband是一款薄、软、低负担的腕带，可以提供有意义的触觉反馈，使其成为AR/VR环境的理想选择。
In this paper we present the design and control of Bellowband, a pneumatic wristband for localized pressure and vibration haptic feedback. The wristband has eight equally spaced pneumatic bellows that extend into the wrist, constructed from layers of polyester thermoplastic polyurethane (TPU), resulting in a flexible, lightweight (11 g) band capable of rendering complex pressure and vibration cues to the user. Each bellow can withstand over 100 kPa, extend over 10 mm, and exert over 10 N of force at zero displacement. Quasi-static analysis is performed to estimate bellow force for a given input pressure and bellow displacement, and the dynamic response is examined experimentally. Finally, we demonstrate the wristband’s ability to deliver various haptic cues to the wrist, including uniform squeeze, uniform vibration, local force, and local vibration. Bellowband is a thin, soft, low-encumbrance wristband that can provide meaningful haptic feedback, making it ideal for AR/VR environments.
