Funded by the ESA MAP programme, the Respiratory Sensor System (RSS) project has successfully developed a miniaturised sensor system for respiratory investigations. The final presentation has been held at ESTEC on 08/04/2008.

Project objectives

The main goals of this project can be summarised as follows:
  • Development of new miniaturised planar sensor elements for O2 incl. flow simultaneously and CO2 (including flow simultaneously) for fast in-situ measurement
  • Integration of the sensors into a breathing mask
  • Development of the electronics for the fast operation and data acquisition
  • Development of the software for sensor operation, data acquisition and analysis
  • Development of sensors for additional gas species (H2 /CO)
  • Commercialisation of the system
The main challenges have been the simultaneous flow measurement and flow cross sensitivities. Especially during phase 2 of the project, many development iterations lead to a very good applicability for the oxygen, CO2 and H2 sensors (including flow sensors respectively).

Project results

The RSS is a robust and easy to use system (very short preparation times), which meets requirements for a possible space application as well as the requirements for terrestrial applications in various fields (e.g. medicine, lung function diagnostics, fitness, combustion control, etc.)This miniaturised and mobile system avoids (for in-situ measurements) typical delay times and has a very fast response time.Its main advantages are:
  • Fast response times for gas measurement t90 < 100ms
  • Low breath resistance
  • Fast flow measurement possible, including flow direction!
The first commercial use of the system is planned by Medisoft in June 2008.
