摘要

柔性传感器已成为人体健康监测、智能家居、人机交互等领域的研究热点。然而，除了提高传感器的灵敏度和应变范围外，定向应变跟踪在实际应用中也是至关重要的。本文将金属N-VO0.9纳米片与银纳米线（Ag NWs）结合，形成互连导电网络。此外，通过预拉伸策略形成的N-VO0.9/Ag NWs具有褶皱和裂纹结构，在暴露于应变时可以引起不同的电变化。因此，所设计的应变传感器除了具有突出的灵敏度、快速的响应时间和出色的循环稳定性外，还具有良好的多向选择性，可以有效地跟踪复杂的身体动作和监测羽毛球发球，显示其在运动训练中的价值。

Wrinkled and cracked sensory structure towards multidirectional strain detection

Flexible sensors have emerged as a research hotspot in areas of human healthcare monitoring, smart home, and human-computer interaction. However, directional strain tracking is also critical in practical situations besides of the improved sensitivity and strain range of the sensor. Herein, metallic N-VO_0.9 nanosheets are combined with silver nanowires (Ag NWs) to form interconnecting conductive network. Furthermore, the N-VO_0.9/Ag NWs with wrinkle and crack structures formed through the pre-stretching strategy, can cause different electrical changes when exposure to strains. Thus, in addition to sensing performance of prominent sensitivity, quick response time, and outstanding cyclic stability, the designed strain sensor harnesses good multi-directional selectivity, effectively tracks intricate body motions and monitors badminton serves, showcasing its value for sports training.
