摘要：
可穿戴的分布式触觉设备旨在提供多点触觉刺激，但难以在最小规模下以足够力度（>1 N）在频率上产生深压感觉且最小化干扰。本文提出了一种从热塑性涂层织物中制造气动执行器阵列的方法。通过将气动进气口路由到织物的共同折叠线上，我们证明了多个气动袋状执行器可以在一次简单的热压操作中形成，而无需使用牺牲阻挡层。该方法可以适应不同执行器直径和间距范围，包括直径仅为8毫米的紧凑型执行器，间距为1毫米，这使得其适用于指尖可穿戴设备。在阻塞力测试中，这些小型气动织物执行器在压强为230kPa时可产生2.1N的力。借助这两种执行器，我们展示了一个应用示例，其中我们调用既独立又累积的刺激，表明可以利用织物执行器阵列来调节可察觉差异的幅度。
英文摘要：
Wearable distributed tactile devices aim to provide multipoint touch stimuli, but struggle to provide sufficient forces (> 1 N) at frequencies to invoke deep pressure sensation with minimal encumbrance at small scales. This work presents a method of fabricating arrays of pneumatic actuators from thermoplastic-coated textiles. By routing pneumatic inlets to a common fold line in the fabric, we demonstrate that multiple pneumatic pouch actuators can be formed in a single simple heat-pressing operation that does not require the use of sacrificial blocking layers. The method accommodates a range of actuator diameters and spacing distances, including as compact as 8 mm diameter actuators spaced 1 mm apart, which enables use in fingertip wearable devices. In a blocked force test, these small pneumatic textile actuators exert 2.1 N when pressurized to 230 kPa. With this pair of actuators, we demonstrate an example application in which we invoke both distinct and summative stimuli, suggesting the possibility of titrating just noticeable difference in amplitude with a textile actuator array.
