German-developed rescue mat to ease CPR efforts

September 9, 2019

Cardiopulmonary resuscitation, or CPR, is an impromptu measure for those experiencing a heart attack. While many people are not confident in performing an emergency CPR for various reasons, a device has been developed by German scientist to simplify the process.

The “Rescue Aid” mat was designed jointly by students and scientists from the Munich University of Applied Sciences (MUAS) and the Fraunhofer Institute for Silicate Research (Fraunhofer ISC). It is to be placed over the affected person’s torso when they are lying down, and will guide a bystander in applying chest compressions through a network of flexible silicone deformation sensors – a strip of LEDs in a panel at the top of the mat will illuminate with each compression, shining in green if the pressure is sufficient or in red if it’s too much. In addition, the panel will beep with each successful compression, just like a metronome to help maintain a steady rhythm.

As initial tests on a resuscitation training mannequin have proven effective, the technology is currently being optimised for real people and will be adapted to fit a variety of body sizes.

Fraunhofer’s Dr. Holger Böse, who worked on the mat, said, “If performed correctly, chest compressions significantly improve the victim’s chances of survival.”
