Clothes represent a unique textile, as they simultaneously provide robustness against our daily activities and comfort (i.e., softness). For electronic devices to be fully integrated into clothes, the devices themselves must be as robust and soft as the clothes themselves. However, to date, no electronic device has ever possessed these properties, because all contain components fabricated from brittle materials, such as metals. Here, we demonstrate robust and soft elastomeric devices where every component possesses elastomeric characteristics with two types of single-walled carbon nanotubes added to provide the necessary electronic properties. Our elastomeric field effect transistors could tolerate every punishment our clothes experience, such as being stretched (elasticity: ∼ 110%), bent, compressed (>4.0 MPa, by a car and heels), impacted (>6.26 kg m/s, by a hammer), and laundered. Our electronic device provides a novel design principle for electronics and wide range applications even in research fields where devices cannot be used.
衣服代表了一种独特的纺织品，因为它们既能提供日常活动所需的坚固性，又能提供舒适感（如柔软度）。为了使电子设备能完全融入衣服中，这些设备本身必须像衣服一样坚固和柔软。然而，迄今为止，还没有任何电子设备具有这些特性，因为它们都包含由脆性材料（如金属）制成的组件。在这里，我们展示了坚固且柔软的弹性体器件，其中每个组件都具有弹性体特性，并添加了两种类型的单壁碳纳米管以提供必要的电子特性。我们的弹性体场效应晶体管能够承受我们衣服所经历的每一种惩罚，例如拉伸（弹性：~110%）、弯曲、压缩（>4.0 MPa，由汽车和高跟鞋施加）、冲击（>6.26 kg m/s，由锤子施加）和洗涤。我们的电子设备为电子学提供了一种新颖的设计原理，并为广泛的应用提供了可能，即使在设备无法使用的研究领域也是如此。
