Scientists have developed flexible sensors that can map real time cardiac activity of a beating heart.

Researchers at the University of Illinois and Northwestern University have developed flexible silicon sensors that can be wrapped around a live, beating heart to get a cardiac map of its electrical activity. The flexible circuits also work when immersed in bodily fluids. This is a significant experiment, as it could replace current heart monitoring techniques which only create a point by point map of the heart. In contrast, the sensor array can map large areas of the heart with more than 2,000 silicon nanomembrane transistors.
