A dual-frequency microporous graphene wearable sensor

This paper describes a dual-frequency wearable graphene antenna sensor that coordinates with each other through 3G and 6G frequencies, providing greater flexibility, stability, and performance optimization than traditional metal single-frequency sensors. In this study, we propose a dual-frequency porous graphene (PG) antenna sensor operating at 6G and 3G frequencies, enabling efficient data transmission, physiological signal detection and adaptive frequency switching in a variety of application scenarios. With its high specific surface area, excellent electrical conductivity and excellent mechanical flexibility, porous graphene offers a promising material for high-performance, wearable antenna sensors. The dual-band capability improves communication quality, reduces signal interference, and optimizes power consumption, making it particularly suitable for health monitoring, smart clothing, motion tracking, and IOT applications.
