3D打印的跑步服使运动员使用编程的智能细菌凉爽

A collaboration between the Massachusetts Institute of Technology (MIT), the National University of Singapore and New Balance Athletics has developed a self-cooling running suit and shoes with the use of 3D printing.

运动服物品利用细菌微生物创建有效自我冷却的材料“与身体协同作用。”

Making of a living garment

在这项特殊的研究中,研究人员借鉴了吸湿性,这意味着“能够从空气中吸收水分”,以及生物荧光,“在紫外光下发光”,细菌的品质可产生空气释放襟翼和可见度。

The base material for both items is latex. To start, E. Coli bacterium microbes are introduced to the materials using a micro 3D printing technique based upon liquid deposition.

干燥后,大肠杆菌细胞自然收缩会导致乳胶弯曲。当引入湿度时,细胞会吸收空气中的水分并变得平坦。

为了量身定制这些动作以适合襟翼的开口和关闭,研究人员覆盖了织物两侧的细菌。这意味着,当干燥时,自然的“弯曲”力与另一侧的相同力匹配,将织物襟翼置于中性封闭状态。

As humidity increases, single cells swell and shrink depending upon exposure to moisture. This causes an imbalance in the structure, where the moistened cells give way to the dryer cells on the opposite side, yielding a bend and opening the cooling flap.

随后的材料层增强了这种产量的柔韧性水平。TPU用于粘结层,网格织物用于在皮肤和西装之间形成空气口袋,并且在核心和后面板中使用了弹性织物。

When humid, the bacteria also exhibits bioluminescent properties, meaning the runner can be easily seen in the dark.

改进和生物制造的可能性

未来的工作将集中在细胞的稳定性上,以确保有效的生活服装在相当长的一段时间内具有可持续性。初步洗涤试验(100个干湿周期)对服装的持续柔韧性显示了积极的结果,但是可以进一步的工作将细菌嵌入织物本身中。

Bacteria – the magic ingredient

As a highly versatile and well documented bacterium, E. Coli is frequently the subject of smart-tech research. Strains of the microbe were used by麻省理工学院研究员Neri Oxman在3D印刷中创建颜色vespersmasks对于Stratasys。美国陆军研究实验室(ARL)也与麻省理工学院合作,正在研究E. Coli’s use to make smart wearable tech for soldiers,,,,和researchers at TU Delft in the Netherlands have developedan inexpensive method for 3D printing strains as a material.
