Abstract

The proliferation of electronic devices and signal jamming technologies in modern warfare poses a substantial threat to the survivability and communication efficiency of traditional military equipment. The development of smart wearable military gear aims to improve electromagnetic interference (EMI) shielding, infrared stealth, and intelligent sensing capabilities, thereby addressing challenges in complex electromagnetic environments. Herein, a lightweight, multifunctional wearable military suit based on carbon nanotube (CNT)/silver nanowire (AgNW) composite foam was fabricated using a combination of electroplating and vacuum-assisted dip-coating techniques. Benefiting from the excellent conductive network and unique multi-scale interconnected framework, the composite foam demonstrated high electrical conductivity (333.3 S/m), low density (0.07 g/cm³), and exceptional EMI shielding (50.12 dB). More importantly, an assembled smart glove could be employed to establish military gesture recognition systems, thereby improving command accuracy and efficiency when integrated with sensors. When as a smart sensor, the composite foam exhibited rapid response time (0.121 s) and excellent sensitivity (0.39 V kPa⁻¹). The application of this technology not only strengthens silent communication capabilities but also paves the way for the development of future military wearable devices, driving innovations towards more intelligent and rapid-response equipment.

可穿戴军用套装用双导电网络增强多功能泡沫装置

现代战争中电子设备和信号干扰技术的激增对传统军事装备的生存能力和通信效率构成了重大威胁。智能可穿戴军事装备的发展旨在提高电磁干扰（EMI）屏蔽、红外隐身和智能传感能力，从而应对复杂电磁环境中的挑战。本文采用电镀和真空辅助浸涂相结合的技术，制备了一种基于碳纳米管(CNT)/银纳米线（AgNW）复合泡沫材料的轻质多功能可穿戴军用服。得益于优异的导电网络和独特的多尺度互连框架，复合泡沫具有高导电性（333.3 S/m），低密度（0.07 g/cm3）和出色的EMI屏蔽（50.12 dB）。更重要的是，组装的智能手套可以用于建立军事手势识别系统，从而提高与传感器集成的指挥精度和效率。作为智能传感器，复合泡沫具有快速的响应时间（0.121 s）和优异的灵敏度（0.39 V kPa−1）。该技术的应用不仅增强了无声通信能力，而且为未来军事可穿戴设备的发展铺平了道路，推动了更智能和快速响应设备的创新。
