Figure6-8_Laboratory setup measurements.zip | CO2 concentration dependency of the photoacoustic sensor signal at different absorption path lengths and diameters | 886,8 kB | ZIP | Öffnen/Download |
Figure9_0-30% CO2 measurement.zip | Comparison of the developed photoacoustic CO2 sensor with the commercial NDIR sensor ExplorIR-W (Gas Sensing Solutions Ltd., United Kingdom) at 1 vol. % concentration vari-ations between 0 and 19 vol. % CO2. The tested gas matrix is a mixture of dry N2 and CO2. Each gas matrix variation was measured for 10 minutes. | 1,79 MB | ZIP | Öffnen/Download |
Figure10_30-70%_Humidity_influence.zip | Comparison of the absolute (a) and normalized (b) signal values of the developed photoacoustic CO2 sensor with the commercial NDIR sensor ExplorIR-W (Gas Sensing Solutions Ltd., United Kingdom) at 10 vol. % concentration variations between 30 and 70 vol. % r.H. The tested gas matrix is a mixture of dry N2 and O2 at 8 vol. % CO2. Each gas matrix variation was measured for 10 minutes and respectively repeated five times. | 574,61 kB | ZIP | Öffnen/Download |
Figure11_0-20%_Oxygen_influence.zip | Comparison of the absolute (a) and normalized (b) signal values of the developed photoacoustic CO2 sensor with the commercial NDIR sensor ExplorIR-W (Gas Sensing Solutions Ltd., United Kingdom) at 5 vol. % concentration variations between 0 and 20 vol. % O2. The tested gas matrix is a mixture of dry N2 and O2 at 8 vol. % CO2. Each gas matrix variation was measured for 10 minutes and respectively repeated five times. | 533,45 kB | ZIP | Öffnen/Download |
Figure12_Skin_measurement_PA_sensor.zip | The slow detector signal change after fixing the miniaturized photoacoustic sensor to the skin surface of the test person. The decrease in the photoacoustic signal indicates the CO2 diffusing out of the skin surface and into the measurement cell of the CO2 sensor. The signal reaches its lowest measured value after 3 hours (181 minutes), which represents the arterialization time of the developed sensor. After 202 minutes the sensor is removed from the skin and the signal abruptly jumps to a value that corresponds to the surrounding CO2 concentration in air. | 69,22 kB | ZIP | Öffnen/Download |
