可穿戴和可贴肤传感设备在运动和健康识别、人机交互以及人工智能方面具有突出的适用性，因此研究的急剧增加。然而，最先进的可穿戴传感器缺乏对易变的可穿戴微气候或多方向机械输入的感测可靠性，这导致在整个实施过程中的次优感测精度。在这项工作中，我们提出了一个组装灵活的应变传感网络的基础上，碳纳米管的配置。该传感器利用其在不同温度、湿度、酸碱水溶液中的传感稳定性，对可穿戴界面的微环境变化具有较高的可靠性。对弯曲、扭曲和压力的响应也是微不足道的，这保证了在实际可穿戴场景中对多方向机械输入的感测可靠性。通过与深度学习和控制系统集成，高性能和生物相容性的应变仪可以精确识别手势并操纵机器人手腕的向上/向下弯曲。它在运动识别和人机交互方面显示出巨大的潜力。
A dramatic proliferation of research is placed on wearable and skin-mountable sensing devices because of the prominent serviceability in motion and health recognition, man-machine interaction, as well as artificial intelligence. State-of-the-art wearable sensors, however, lack sensing reliability towards either fickle wearable microclimate or multi-direction mechanical inputs, which leads to a suboptimal sensing accuracy throughout the implementation. In this work, we propose an assembly-flexible strain sensing network based on a carbon nanotube percolated configuration. The sensor possesses high reliability upon microenvironment change of wearable interfaces by taking advantage of the sensing stability in various temperatures, humidity, aqueous acid, and alkaline solutions. The response to bending, twisting, and pressuring is also marginal, guaranteeing sensing dependability against multi-direction mechanical inputs in practical wearable scenarios. By being integrated with deep learning and control systems, the high-performance and biocompatible strain gauges can precisely identify hand gestures and manipulate the upwards/downwards bending of a robot wrist. It demonstrates huge potential in motion identification and man-machine interaction.
