On February 25th, groundbreaking research utilizing 3D printers was published by John Rogers of University of Illinois in Nature Communications. The article, 3D-printed 'electronic glove' could help keep your heart beating forever, summarizes how researchers have use computer modeling technology in tandem with a 3D printer to create a synthetic membrane capable of sustaining a heart beat indefinitely. A membrane custom made to fit around a heart is outfitted with a series of sensors and electrodes able to detect and measure the heart's electrical activity.

This technology has come a long way since it was first introduced as the 'cardiac sock' in the 1980's. From the once crude sleeves, Roger's has revamped the 'cardiac sock' concept by exploiting bends, turns and curls in his lay out design of electronics giving them elastic-like properties. With a tight fit achieved through 3D printing, Roger's has created what he compares to the naturally occurring pericardium or double walled membrane surrounding the heart.

For now, the 'electronic glove' will be used as a research tool to better understand how the heart reacts to different variables. In the future, one could imagine that such technology could replace pacemakers, deliver electric shocks in cardiac arrest events, or prevent heart attacks all together by regulating the heart beat of at-risk individuals.

For you, this innovation could become a career search looking into the pathways into materials science, computer modeling, biomedical engineering, and 3D computer generated imaging and printing.  Don't stop with the act of gaining information.  Let the new information guide you to the next steps.  In case you need some support moving from inspiration to perspiration, let an article on the SACNAS website entitled Building your Individual Development Plan (IDP):  A Guide for Undergraduate Students guide you through the process!
