提出了一种受排版印刷启发而批量生产透明导电碳纳米管(CNT)薄膜的干法转移方法。基于碳纳米管薄膜的应变传感器具有很高的延伸性和重复性(85%应变时的应变系数高达9960)。这些超薄应变传感器可以检测人体运动、声音和脉搏，在可穿戴设备中具有广阔的应用前景。本文的在线版本(10.1007/s408200190323-8)包含补充材料，可供授权用户使用。灵活、可穿戴的传感器件在脉搏测量、运动检测、语音识别等生物监测领域具有广阔的应用前景。近年来，为了提高传感器的灵敏度、灵活性和重复性，人们对传感器进行了许多重大改进。然而，直接在柔性衬底上制备图案化传感器仍然是极其复杂和困难的。受印刷术的启发，提出了一种低成本、环保的批量生产透明导电碳纳米管(CNT)薄膜的冲压方法。在这种干式转移策略中，多孔碳纳米管块既用作密封件又用作墨水；Ecoflex膜作为目标基材。在冲压工艺之前，通过在碳纳米管封口上雕刻目标图案，可以很容易地在聚合物衬底上制造出设计良好的碳纳米管图案。此外，该碳纳米管薄膜还可以直接用于制作超薄(300μm)应变传感器。该应变传感器具有高灵敏度，85%应变时的量规系数(GF)高达9960，高伸长性(>； 200%)和重复性(>； 5000次)。它已被用于测量脉搏信号和检测关节运动，在柔性和可穿戴电子设备中具有广阔的应用前景。本文的在线版本(10.1007/s408200190323-8)包含补充材料，可供授权用户使用。
A dry transfer method for the mass production of transparent conductive carbon nanotube (CNT) films inspired by typography has been proposed. The strain sensors based on the CNT films have high stretchability and repeatability (gauge factor up to 9960 at 85% strain). These ultrathin strain sensors can detect human motion, sound, and pulse, suggesting promising application prospects in wearable devices. The online version of this article (10.1007/s40820-019-0323-8) contains supplementary material, which is available to authorized users. Flexible and wearable sensing devices have broad application prospects in bio-monitoring such as pulse measurement, motion detection and voice recognition. In recent years, many significant improvements had been made to enhance the sensor’s performance including sensitivity, flexibility and repeatability. However, it is still extremely complicated and difficult to prepare a patterned sensor directly on a flexible substrate. Herein, inspired by typography, a low-cost, environmentally friendly stamping method for the mass production of transparent conductive carbon nanotube (CNT) film is proposed. In this dry transfer strategy, a porous CNT block was used as both the seal and the ink; and Ecoflex film was served as an object substrate. Well-designed CNT patterns can be easily fabricated on the polymer substrate by engraving the target pattern on the CNT seal before the stamping process. Moreover, the CNT film can be directly used to fabricate ultrathin (300 μm) strain sensor. This strain sensor possesses high sensitivity with a gauge factor (GF) up to 9960 at 85% strain, high stretchability (> 200%) and repeatability (> 5000 cycles). It has been used to measure pulse signals and detect joint motion, suggesting promising application prospects in flexible and wearable electronic devices.
