摘      要：Flexible wearable electronics were developed for applications such as electronic skins,human-machine interactions,healthcare monitoring,and anti-infection *** conventional materials showed impermeability,single sensing ability,and no designated therapy,which hindered their *** it was still a great challenge to develop electronic devices with multifunctional sensing properties and self-driven anti-infection ***,flexible and breathable on-skin electronic devices for multifunctional fabric based sensing and self-driven designated anti-infection therapy were prepared successfully with cellulose nanocrystals/iron(Ⅲ)ion/polyvinyl alcohol(CNC/Fe^(3+)/PVA)*** resultant composite films possessed robust mechanical performances,outstanding conductivity,and distinguished breathability(3.03 kg/(m^(2)·d)),which benefited from the multiple interactions of weak hydrogen bonds and Fe^(3+) chelation and synergistic effects among CNC,polyaniline(PANI),and ***,the film could be assembled as a multifunctional sensor to actively monitor real-time physical and infection related signals such as temperature,moisture,pH,NH3,and human movements even at sweat *** importantly,this multifunctional device could act as a self-driven therapist to eliminate bacterial by the release of Fe^(3+),which was driven by the damage of metal coordination Fe-O bonds due to the high temperature caused by infection at wound ***,the composite films had potential versatile applications in electronic skins,smart wound dressings,human-machine interactions,and self-driven anti-infection therapy.
