With the fast development of the smart lifestyle in recent years, simple and flexible body condition monitoring has become more and more important. However, currently, commercially available motion-sensing devices always lack flexibility or at a high cost. This article has fully explored the merits of a commercial and easily available material of carbon fiber powder (CFP) and prepared CFP-based screen printing inks. This conductive ink can be directly and quickly printed onto a variety of different flexible common substrates, such as paper, cotton fabrics, etc., to prepare flexible sensors. At the same time, as a result of the good photothermal performance and conductivity of CFP, the printed flexible sensors have fast and stable performance on thermal and human motion detection. The use of CFP as the smart element to construct a wearable device will offer a choice for the intelligent industry.

基于商用碳纤维粉末墨水的高灵敏度、稳定的柔性智能传感器

近年来，随着智能生活方式的快速发展，简单、灵活的身体状况监测变得越来越重要。然而，目前市售的运动传感设备总是缺乏灵活性或成本较高。本文充分探讨了碳纤维粉末（CFP）这一商业化且易于获得的材料的优点，并制备了基于CFP的丝网印刷油墨。这种导电油墨可以直接快速地印刷到多种不同的柔性通用基材上，如纸张、棉织物等，以制备柔性传感器。同时，由于CFP良好的光热性能和导电性，印刷柔性传感器在热检测和人体运动检测方面具有快速稳定的性能。使用CFP作为智能元件构建可穿戴设备将为智能产业提供一种选择。
