Wearable and elastic pressure sensors have caused widespread concern due to the popularity of smart terminals and human health monitoring. To obtain a flexible pressure sensor with a wide detection region and outstanding sensitivity, exploring new materials and novel structures has become the first choice for the research. Here, a wearable and flexible MXene fibrous network pressure sensor (MFNS) with a high sensitivity and wide detection region is reported. The holistic fiber network is composed of pure MXene fibers; among them, MXene fibers were prepared by wet-spinning of MXene nanosheets. The MFNS exhibits a high sensitivity in a wide detection region (51 kPa for 14.7 kPa and 427 kPa within the 14.7-19.9 kPa range), a low detection limit (8 Pa), a robust durability (10,000 cycles), and a prompt response (95 ms). Due to the superior performance of MFNS, it also proves prospective applications for human motion signal detection (such as swallowing, pulse beat, and joint motion) and measuring pressure distribution. This work provides an effective way to fabricate a high-performance pressure sensor for human-machine interactions, personal healthcare monitoring, and multitouch devices.
由于智能终端的普及和人体健康监测的需求，可穿戴弹性压力传感器受到了广泛关注。为了获得具有宽检测区域和出色灵敏度的柔性压力传感器，探索新材料和新颖结构已成为研究的首要选择。在此，报道了一种具有高灵敏度和宽检测区域的可穿戴柔性MXene纤维网络压力传感器（MFNS）。整体纤维网络由纯MXene纤维组成；其中，MXene纤维通过MXene纳米片的湿法纺丝制备。MFNS在宽检测区域（14.7 kPa范围内，14.7 kPa时为51 kPa，14.7 - 19.9 kPa范围内为427 kPa）具有高灵敏度、低检测限（8 Pa）、强大的耐久性（10,000次循环）和快速响应（95 ms）。由于MFNS的优异性能，它在人体运动信号检测（如吞咽、脉搏跳动和关节运动）以及压力分布测量方面也显示出潜在应用。这项工作为制造用于人机交互、个人医疗保健监测和多点触摸设备的高性能压力传感器提供了一种有效方法。
