Varied Excitation for the Improving of Information Extraction from Signals of Single Sensors

Keywords: sensor signal processing, model-based signal processing, control parameter, impedance spectroscopy

Different approaches can be pursued in order to improve sensory information. The approach of this work is using one single sensor element under varied excitation, such as current or frequency. The dependence of the sensor output on the excitation can be used to separate the effects according to their different reactions on the excitation. Changes in the dependence of the sensor output on excitation can be identified and utilized for self-test and self-calibration. This kind of sensor systems called Varied Input Sensor systems (VIS) closes the gap between single sensors and multi-sensor systems. The development process of this kind of sensor systems needs special care for a robust and undisturbed function.
