It is important to size and optimize the testing chamber in order to ensure a qualified sensor response measurement. Indeed, the amplitude, as well as the response and recovery times are very dependent on the testing chamber. In this study, we show that by optimizing the design and reducing the volume of the testing chamber, the responses of metal oxide microsensors are highly enhanced and faster, and therefore closer to the real behavior of the sensor.
