Some pulsed tissues are replaced with non-pulsed damaged tissues that may endanger the heart function after a heart attack. The restoration is performed by a patch tissue to repair defective tissues. It is supposed to attach to the outside of the heart and connect to the wounded area. The patch is made of a conductive polymer on which a separate electrical polymer called “alginate” through a process called 3D bioprinter was fabricated. The mechanism of the prepared patch for biological and cell behavior needs to be investigated.
