Abstract
With the increasing incidence of cardiovascular events, especially for cardiac arrest and sudden death, the importance of external defibrillator has been greatly recognized. While the current electrodes used in external defibrillator are mainly rigid electrode generating large resistance in the interface between the electrode and the electrical stimulation is unable to be effectively delivered to the target area and even cauterize the skin. In this work, we conducted the adhesive patterning liquid metal flexible electrode for external defibrillator and ECG measurement, the COSMOL simulation analysis of ventricular fibrillation model suggested that the LM flexible electrode can assure the same current distribution and energy delivery, meanwhile requiring less energy input and avoiding skin burn. Furthermore, we verified the better signal stability and certain robustness to motion of liquid metal flexible electrode when measuring electrocardiogram (ECG) compared to the conventional AgCI electrode.
