导电纺织纱线因其用作柔性和可穿戴传感器而不损害普通纺织品的性能和舒适性而特别令人感兴趣。然而，人体的精细动作的检测是相当具有挑战性的，因为它需要传感器的相对较高的灵敏度和稳定性。在此，通过将N掺杂的rGO和聚多巴胺涂覆的碳纳米管装载到硅橡胶管中，制备了高灵敏度、超稳定且极其耐用的压阻式可穿戴传感器。由此产生的可穿戴传感器显示出以良好的灵敏度和可重复性感测细微运动或刺激的优异能力。此外，通过弯曲直导电硅橡胶管（CSRT）成三种不同的模式，它的灵敏度，然后显着增加。最后，CSRT被发现能够感测心肺信号，这表明该传感器将是实现下一代个性化医疗保健应用的生物信号感测的重要一步。
Electroconductive textile yarns are of particular interest for their use as flexible and wearable sensors without compromising the properties and comfort of usual textiles. However, the detection of fine actions of the human body is quite challenging since it requires both the relatively higher sensitivity and stability of the sensor. Herein, highly sensitive, ultra-stable, and extremely durable piezoresistive wearable sensors were prepared by loading N-doped rGO and polydopamine-coated carbon nanotubes into silicon rubber tube. The wearable sensors thus produced show an excellent ability to sense subtle movement or stimuli with good sensitivity and repeatability. Furthermore, by bending the straight conductive silicon rubber tube (CSRT) into three different patterns, its sensitivity was then dramatically increased. Finally, the CSRT was found capable of sensing cardiorespiratory signals, indicating that the sensor would be an important step toward realizing bio-signal sensing for next-generation personalized health care applications.
