Smart electrochemical oxygen sensor for personal protective equipment

Self contained closed circuit rebreathers are life supporting breathing systems, where the exhaled gas is recycled by filtering CO2 and replacing metabolized O2. For the O2 injection control galvanic O2 sensors are used to measure the partial pressure of O2. A malfunction of the sensors can lead to a gas mixture beyond life supporting limits which is life threatening. Galvanic O2 sensors are often...
