Demo-medVer – Decentralized medical care

A Fraunhofer joint project for the systemically integrated medical care of the population during a pandemic and in crisis and disaster situations.

The aim of the subprojects MATSE and OzoSter is the utilization of diamond electrodes and plasma sources in a mobile ozone unit in the form of a backpack sprayer (OzoSter; up to 1 mg/l dissolved ozone in single-pass) as well as in a storage system for the supply and extraction of hypochlorite for surface disinfection and for the emergency chlorination of wastewater as required (MATSE; 5% NaOCl in batch operation).


With the aid of diamond electrodes, the disinfectants are generated directly in the water without the addition of chemicals, whereby the concentration of the oxidizing agents is adjusted solely by means of the specific charge. In addition, plasma sources are employed to generate so-called plasma-activated water, which is capable of inactivating bacteria and viruses as a result of the reactive species it contains (including ozone). Whereas ozone can be used for the disinfection of surfaces, hypochlorite is preferable for supply and transfer to third parties due to its long-term stability.itte.

Added value 

As a result, two disinfection units are available as components of a modular system which can be individually adapted to the requirements of the deployment site (industrialized, emerging or developing country), the reason for deployment (pandemic, environmental or severe weather disaster) as well as the crisis-management personnel (THW, rescue service) and the infrastructure available on site (electricity, water, etc.).

Press release

Fraunhofer is developing a mobile medical care system

Mobile, distributed systems that provide medical care to the public can be a crucial addition to the existing healthcare infrastructure in crises and emergencies such as the current Corona pandemic.  Six Fraunhofer Institutes have joined forces and are developing an integrated system for mobile, distributed medical care in the Demo-medVer project.
