Ionic liquid regenerated cellulose membrane electroless plated by silver layer for ECG signal monitoring

Nowadays, more and attention has been paid to flexible electrodes, which can be used make wearable devices so as monitor health signals, such those in ECG, EMG EEG. However, the contact impedance of many membrane electrodes is high due bad fit between sensors skin, or poor sensitivity caused by low conductivity. Therefore, we fabricated a skin-like conductive electrode via electroless silver plating on surface regenerated cellulose membrane, was prepared from dissolved ionic liquid [Bmim]Cl. The as-prepared biocompatible with skin-electrode dry for long time. Its at 700 Hz only 8 kΩ/cm2 conductivity reaches 252 s/cm. After 5 h wearing, electrode-skin 10 when 0.20 mol/L AgNO3 used. In short, not ensure stable clear ECG signals but also greatly reduce electrode–skin long-term monitoring.
