Abstract

A method of providing localised haptic feedback at precise locations on the body, utilising a lightweight textile garment is presented in this short paper. The textile comprises of subtly integrated actuator yarns (HaptiYarns) which are controlled by electropneumatic circuitry. Each yarn has two functional layers, an inner porous textile layer with limited extensibility and a second, durable outer layer made from an extensible elastomer. The HaptiYarns can provide radial forces and a maximum radial displacement of 28.09 ± 0.14 mm. It was found that the intrinsic addition of graphite powder (5% by weight), during elastomer preparation, offered better resistance to layer delamination and increased the ability of the yarn to withstand higher internal air pressures by 48%. Both the graphite-filled composite and the graphite free yarns demonstrated high durability, withstanding cyclic testing of >7500 cycles while having no significant impact on the force feedback. Finally, a wearable prototype knitted textile garment is presented with eight HaptiYarns subtly integrated within it and connected to a virtual reality (VR) program providing an immersive haptic experience. These yarns offer the potential to transform everyday clothing into wearable haptic devices with potential to revolutionise healthcare, VR-based training, gaming, and entertainment sectors.

HaptiYarn：开发可将日常纺织品转化为触觉设备的执行器纱线。

本短文介绍了一种利用轻质纺织服装在身体精确位置提供局部触觉反馈的方法。这种纺织品由微妙集成的致动器纱线（HaptiYarns）组成，这些纱线由电气动电路控制。每根纱线都有两个功能层，一个是具有有限延伸性的多孔纺织内层，另一个是由可延伸弹性体制成的耐用外层。HaptiYarns 可以提供径向力和 28.09 ± 0.14 毫米的最大径向位移。研究发现，在弹性体制备过程中添加石墨粉（按重量计为 5%），可以更好地防止层间分层，并将纱线承受较高内部气压的能力提高 48%。填充石墨的复合材料和不含石墨的纱线都具有很高的耐用性，可承受大于 7500 次的循环测试，同时对力反馈没有明显影响。最后，展示了一件可穿戴的针织服装原型，服装中巧妙地集成了八根 HaptiYarns，并与虚拟现实（VR）程序相连，提供了身临其境的触觉体验。这些纱线具有将日常服装改造成可穿戴触觉设备的潜力，有望为医疗保健、基于 VR 的培训、游戏和娱乐行业带来变革。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
