摘要：Flexible conductive films often suffer from poor conformability, limited biocompatibility, and unstable electrical conductivity, which hinder their application in dynamic biointerfaces. To address these limitations, this work presents a simple and efficient strategy to fabricate an ultrathin, sandwich-structured multifunctional flexible conductive film (FCF) that achieves conformal integration with various biointerfaces and flexible devices. A stable interlayer integration with high conductivity is achieved by ultrasonically pretreating EGaIn (Ga75In25) with MOF particles in a binder-free manner. The film can clamp tightly into joint areas for real-time monitoring of joint movement. Furthermore, it may also form good quality electrical contact with the heart and brain, allowing high-quality electrocardiogram (ECG) and electroencephalogram (EEG) recording. The composite film showed excellent electromechanical stability as it can perform well through 2000 stretch cycles (0-10% strain) and 24 h water flow erosion. Tests for cytocompatibility have confirmed its excellent biocompatibility together with the remarkable stability of the EEG recording for over 2 weeks. The FCF successfully overcomes traditional compatibility challenges found in soft electronic devices attached to complex biological surfaces, enabling large-scale multisite long-term physiological monitoring.
