Graphene-based sensors provide the foundation for human-machine interaction

Caption

Hierarchical rGMAXn/rGMXn fibrous felts with bioinspired “columnar cactus” structures via molten salt-assisted synthesis and in-situ etching, achieving breakthrough EMA performance (RL >54.4 dB, EAB >5.31 GHz at 10 wt.%) by precisely regulating MXene content and fiber filling content to optimize conductive networks and multi-scale loss mechanisms. The cross-scale design overcomes the efficiency-bandwidth trade-off in MXene absorbers and establishes a new paradigm for lightweight electromagnetic protection in aerospace and wearable electronics.
