Rethinking the Brain Pacemaker: How Better Materials Can Improve Signals

In this week’s AIP Advances, researchers at the University of Tabriz created organic materials for brain and heart pacemakers, which rely on uninterrupted signal delivery to be effective. Using a plastic base known as polypropylene, the researchers added a specially formulated clay called Montmorillonite and different ratios of graphene, one of the strongest lightweight materials. They created five different materials that could be performance-tested and took detailed measurements of the structure of the composite materials using scanning electron microscopy.
