About CorPatch®

What to do when a loved one is not breathing and lies unconscious on the ground? If you feel insecure and uncertain about how to perform CPR in case of cardiac arrest, you are not alone. It is an extremely stressful situation, where chances of survival decrease for every minute, the brain lacks blood and oxygen.

With CorPatch® we aim to reduce insecurities and guide you to perform quality CPR from the first crucial minutes of a cardiac arrest. CorPatch® and the free app can guide you to check for life signs, call 1-1-2 and perform CPR using a unique feedback system.


We want to save lives and increase survival rates through high-quality CPR in case of cardiac arrest.


We want to prepare and empower anyone to provide high-quality CPR with CorPatch® in case of cardiac arrest by:

Making anyone familiar with how to perform effective CPR

Giving confidence to anyone to act and help them make a difference

Removing the anxiety when a cardiac arrest occurs

SmartResQ is the company behind CorPatch®, which has evolved from the urge to significantly improve chances of survival after cardiac arrest.

In 2014, the idea came to life by inventor Prof. Dr. Michael Müller, head physician in emergency medicine in Freiburg, Germany. He recognized the need to improve early bystander CPR quality in case of cardiac arrest. A few years later, Dr. Matthias Roth, entrepreneur B.Sc. Per Schorling and technological lead Dipl.Ing. Thomas Hötzel joined the vision to save more lives after cardiac arrest.

CorPatch® is developed, tested and produced in accordance with most recent medical standards and user preferences.

In 2017, the very first research showed how well CorPatch® works and since then, development has continued steadily onwards. Now, the accurate and rock-solid technology is ready to help save lives in case of cardiac arrest.

The team behind CorPatch® are experts with solid experience within their field. They share a mutual passion to save life after cardiac arrest and set high standards for themselves as well as the technology and development of CorPatch®.
