CHAMPAIGN, Ill. Cardiologists may soon be able to place sensitive electronics inside their patients' hearts with minimal invasiveness, enabling more sophisticated and efficient diagnosis and treatment of arrhythmias. A team of materials scientists, mechanical and electrical engineers, and physicians has successfully integrated stretchable electronics technology with standard endocardial balloon catheters. Led by John A. Rogers, the Lee J. Flory-Founder Chair in Engineering at Illinois, the team published its work in the March 6 online edition of Nature Materials. The team previously demonstrated a sensor-laden sheet that could laminate to the surface of the heart in 2010. Now they have expanded their technology to endocardial balloon catheters, one of the most common, least-invasive devices for cardiac procedures. Catheters are long, flexible tubes that can be threaded through a vein or artery to reach the inside of the heart.
