Membrane Pacemakers

Researchers from Washington University in St. Louis developed the new membrane to wrap around hearts like a flexible net. This spiderweb-like network of specialized electrodes continuously monitors the heart’s electrical activity and easily expands and contracts with the heart. This technological membrane can also apply a high-definition therapy to stop heart attacks or other irregular heart problems.
