Wireless technologies-supported printed flexible electronics are crucial for the Internet of Things (IoTs), human-machine interaction, wearable and biomedical applications. However, challenges to existing printing approaches remain, such as low precision, difficulty in conformal printing, complex ink formulations processes. Here we present a room-temperature direct strategy wireless electronics, where distinct high-performance functional modules (e.g., antennas, micro-supercapacitors, sensors) can be fabricated with high resolution further integrated on various flat/curved substrates. The additive-free titanium carbide (Ti3C2Tx) MXene aqueous inks regulated large single-layer ratio (>90%) narrow flake size distribution, offering metallic conductivity (~6, 900 S cm-1) ultrafine-printed tracks (3 μm line gap 0.43% spatial uniformity) without annealing. In particular, build an all-MXene-printed system capable communication, energy harvesting, smart sensing. This work opens door high-precision additive manufacturing at room temperature.
