智能织物和互动纺织品作为一种新兴的材料，由于其多功能性而引起了人们极大的兴趣。在此，通过将功能性杂化碳纳米材料和压阻材料集成在商业纺织品的基础上，制造了高度鲁棒的无线柔性应变传感器。具体地，采用能够在大面积织物上产生均匀涂层的可溶液加工的喷涂辅助涂覆方法。基于纺织品的应变传感器表现出高度稳定和即时的响应范围广泛的弯曲曲率和ZnO纳米线的结构特性，因为它们不同的偏转行为。进一步证明了其在商业织物上的服用性能。所制备的传感器对不同的身体运动有很好的响应，可以准确检测应变幅度，甚至可以通过连接到无线发射器来扩展其在无线遥感中的可行性。用功能性纳米材料对纺织品进行改性的新方法可以为生产基于纺织品的电子产品提供可行的方法，而无需采用任何复杂的制造工艺，并且通过利用各种传感元件进一步利用各种功能。
Smart fabrics and interactive textiles have attracted great interest as a newly emergent material because of their multifunctional capabilities. Herein, a highly robust wireless flexible strain sensor on the basis of commercial textile by the integration of functional hybrid carbon nanomaterials and piezoresistive material is fabricated. Specifically, a solution-processable spray-assisted coating approach that enables the creation of a uniform coating over a large area of fabrics is employed. The textile-based strain sensor exhibits a highly stable and immediate response over a wide range of bending curvatures and structural properties of ZnO nanowires because of their different deflection behaviors. The wearing performance with attaching on commercial fabrics is further demonstrated. The as-prepared sensor responds well to diverse body motions with accurate detection of strain magnitude and even extends its viability in wireless remote sensing by connecting to a wireless transmitter. The novel approach for the modification of textiles with functional nanomaterials may provide a feasible approach for the production of textile-based electronics without employing any sophisticated fabrication processes, and it further exploits the diverse functionalities by utilizing various sensing components.
