Wearable and stretchable electronics enabled by MXene-PVA films layer-by-layer assembly with integrated UV, thermal, and mechanical sensing.

We integrate MXene with polyvinyl alcohol (PVA) through a meticulous layer-by-layer assembly process, not only enhancing the mechanical flexibility and robustness of MXene but also significantly improving its environmental stability. The MX-PVA films exhibit multi-responsiveness to UV light, temperature, and mechanical pressure, highlighting their potential for use in wearable electronics.
