Winter term 2007 / 2008
   
    Chemical sensors (Monday, 8:15 - 9:00, Room 204)

    The lectures are concerned with basic principles, design and main applications of chemical and biochemical sensors. The following aspects are covered:

    · Definitions, classification, importance of sensors within the range of analytical methods
    · Sensor characteristics
    · Physical principles and phenomena that can be exploited for sensors (hall effect, piezoelectric effect, pyroelectric effect, ultrasound ...)
    · Measuring aspects (simple electric circuits, operational amplifiers, measurements of small current and voltage signals)
    · Electrochemical sensors I (potentiometric)
    · Electrochemical sensors II (amperometric)
    · Optical devices and mass-sensitive sensors (SAW)
    · Gas sensors and the concept of “electronic noses”
    · Biosensors I (principles)
    · Biosensors II (advanced concepts and sensors for in vivo analysis)
    · Sensor fabrication technology (materials, thin film and thick film technology, screen printing, LIGA ...)
