Conventional cardiac implants have modulated cardiac conduction and following contraction process in heart failure patients. However, the transvenous lead implantation is incompatible with large-area electrophysiological mapping and selective multi-channel stimulations. Moreover, there are several lead-related drawbacks in conventional cardiac implants. Here, this poster presentation introduces fabrication of soft and conductive epicardial mesh electrodes using a stretchable low-impedance nanocomposite comprising silver-gold core-shell nanowires with platinum black in an elastomeric matrix. The soft and conductive epicardial mesh electrodes with low impedance presented a potential solution to the abovementioned issues. The high stretchability, conductivity, biocompatibility, and electrochemical properties of the elastomeric nanocomposite enable excellent quality of electrogram recording and electric stimulations on the animal heart. The various cardiac arrhythmias can be monitored and successfully treated with pacing. Electrical pacing using epicardial mesh electrodes supported not only treating arrhythmias but also the effective contraction of the heart. |
