The flexible radio frequency (RF) wireless antennas used as sensors, which can detect signal variation resulting from the deformation of the antenna, have attracted increasing attention with the development of wearable electronic devices and the Internet of Things (IoT). However, miniaturization and sensitivity issues restrict the development of flexible RF sensors. In this work, we demonstrate the application of a flexible and highly conductive graphene-assembled film (GAF) for antenna design. The GAF with a high conductivity of 106 S/m has the advantages of light weight, high flexibility, and superb mechanical stability. As a result, a small-size (50 mm × 50 mm) and flexible GAF-based antenna operating at 3.13–4.42 GHz is achieved, and this GAF antenna-based wireless wearable sensor shows high strain sensitivities of 34.9 for tensile bending and 35.6 for compressive bending. Furthermore, this sensor exhibits good mechanical flexibility and structural stability after a 100-cycle bending test when attached to the back of the hand and the wrist, which demonstrates broad application prospects in health-monitoring devices, electronic skins, and smart robotics.

随着可穿戴电子设备和物联网（IoT）的发展，用作传感器的柔性射频（RF）无线天线可以检测因天线变形而产生的信号变化，受到越来越多的关注。然而，小型化和灵敏度问题限制了柔性射频传感器的发展。在这项工作中，我们展示了柔性高导电石墨烯组装薄膜（GAF）在天线设计中的应用。具有10 6 S/m高电导率的GAF具有重量轻、柔韧性高和机械稳定性极佳的优点。结果，实现了工作频率为 3.13-4.42 GHz 的小尺寸（50 mm × 50 mm）、灵活的基于 GAF 的天线，并且这种基于 GAF 天线的无线可穿戴传感器表现出拉伸弯曲 34.9 和 35.6 的高应变灵敏度。用于压缩弯曲。此外，该传感器贴在手背和手腕上，经过100次弯曲测试后，表现出良好的机械灵活性和结构稳定性，在健康监测设备、电子皮肤和智能机器人等领域具有广阔的应用前景。
