O2 SENSOR PATORound the chip a flow channel has been created using specially formed ceramic parts, allowing the gas to be led past the sensor without actually flowing over the sensor surface. In this way, a fast response time has been achieved for refreshing the gas composition around the sensor, while avoiding that the sensor acts as a flow sensor. Thus, a true and accurate thermal conductivity measurement is carried out. Oxygen concentration is determined at a rate fast enough for breathing applications at a resolution of the order of 0.5 % oxygen concentration. This is achieved in the presence of.
