With the emergence of human interface technology, the development of new applications based on stretchable electronics such as conformal biosensors and rollable displays are required. However, the difficulty in developing semiconducting materials with high stretchability required for such applications has restricted the range of applications of stretchable electronics. Here, we present stretchable, printable, and transparent transistors composed of monolithically patterned graphene films. This material offers excellent mechanical, electrical, and optical properties, capable of use as semiconducting channels as well as the source/drain electrodes. Such monolithic graphene transistors show hole and electron mobilities of 1188 ± 136 and 422 ± 52 cm(2)/(V s), respectively, with stable operation at stretching up to 5% even after 1000 or more cycles.
随着人机接口技术的出现，需要开发基于可拉伸电子学的新型应用，例如贴合式生物传感器和可卷曲显示器。然而，开发具有此类应用所需的高拉伸性的半导体材料的困难限制了可拉伸电子产品的应用范围。在这里，我们提出了由整体图案化的石墨烯薄膜组成的可拉伸、可打印和透明晶体管。这种材料具有优异的机械、电气和光学性能，可用作半导体通道以及源/漏电极。这种整体式石墨烯晶体管的空穴和电子迁移率分别为 1188±136 和 422±52cm2/（V s），在拉伸至 5%甚至经过 1000 次以上循环后仍能稳定工作。
