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).

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.
