Online washing process monitoring with wireless textile impedance measurement

In this paper a sensor system for the in-situ monitoring of dirt removal in the running washing process is presented. In this work, a sensor is presented for adjustment or optimization of washing processes in textile service companies. The developed impedimetric performance sensor consists of a dirt and reference sensor area as well as a measuring and RFID communication module. At the sensor areas the impedance is measured during the washing process, recorded and transferred to an external evaluation unit. The impedance values can be used to determine the dirt removal during the washing process.
