Lehrinhalte
From the content:
1. General introduction to the topic. Definitions: sensors, chemical sensors.
Principle of construction (receptor and transducer). Gas sensors. Their
importance (why, what for, application areas). Examples. Basic characteristics
(response, signal, sensitivity).
2. Classification (due to the transduction principles; materials; applications).
Principle of detection. Physico-chemical processes responsible for the
detection.
3. Sensor fabrication. Micromachining. MEMS. CMOS. Deposition of sensing layers.
4. Resistive sensors (chemoresistors). Semiconducting oxides (SnO2). Taguchi
sensors. Microplatforms. Conducting polymers (phthalocyanine). Biomimicry.
5. Capacitive sensors. Gas-sensitive polymers. Impedance spectroscopy.
Humidity detectors.
6. Electrochemical sensors. Ionic conductors. Lambda-sonde. Water vapour detection.
7. Work function changes. Field-effect transistors. Hydrogen sensors.
8. Thermochemical (calorimetric) sensors. Pellistors. Methane detection.
9. Mass sensors. Quartz microbalance. Surface and bulk acoustic waves.
10. Optical sensors. Non-dispersive IR. CO2 sensors. Climate control systems in cars.
11. Sensor arrays. Electronic noses. Data treatment. Multivariate analysis.
