近日，瑞士洛桑聯邦理工學院的Herbert Shea課題組成功研制了用于可穿戴流體系統的纖維泵。相關研究成果已于2023年3月31日在國際權威學術期刊《科學》上發表。

該研究團隊開發了一種可伸縮纖維形式的流體泵，能夠將壓力源直接集成到紡織品中，實現了無線可穿戴的流體控制。這種泵由連續螺旋電極嵌入薄彈性管道壁內組成，通過電荷注入電流電動力學原理靜音下產生壓力。每米纖維可產生100千帕的壓力，流量接近55毫升/分鐘，相當于15瓦/千克的功率密度。此外，這種泵的設計自由度相當大，可以實現可穿戴觸覺、機械活性織物和溫調紡織品等應用。

據介紹，將加壓流體電路融入紡織品中可以在便捷的可穿戴形式中實現肌肉支撐、溫度調節和觸覺反饋。然而，常規的剛性泵由于其產生的噪音和振動而不適用于大多數可穿戴設備。

Title: Fiber pumps for wearable fluidic systems

Abstract: Incorporating pressurized fluidic circuits into textiles can enable muscular support, thermoregulation, and haptic feedback in a convenient wearable form factor. However, conventional rigid pumps, with their associated noise and vibration, are unsuitable for most wearables. We report fluidic pumps in the form of stretchable fibers. This allows pressure sources to be integrated directly into textiles, enabling untethered wearable fluidics. Our pumps consist of continuous helical electrodes embedded within the walls of thin elastomer tubing and generate pressure silently through charge-injection electrohydrodynamics. Each meter of fiber generates 100 kilopascals of pressure, and flow rates approaching 55 milliliters per minute are possible, which is equivalent to a power density of 15 watts per kilogram. The benefits in design freedom are considerable, which we illustrate with demonstrations of wearable haptics, mechanically active fabrics, and thermoregulatory textiles.
