Capacitive Sensors: Principles and Applications

This lecture covers the principles and applications of capacitive sensors, focusing on electrode arrangements, capacitance variations, liquid level sensors, electrostatic force, and capacitive accelerometers. It explains the configuration of electrodes, displacement sensitivity, different sensor geometries, and technologies for capacitive accelerometers. The lecture also discusses error sources, non-linearities, and measuring circuits for capacitive accelerometers, as well as the transfer function of the servo accelerometer.
