Master's Thesis - Development of an Embedded EIS Measuring System for Quality Detection of Liquids

We're winter holders, the purse specialist from Meckenbeuren. With over 2,000 employees at over 40 locations in all over the world, we are among the market leaders of the kitchen industry. Our employees work day after day perfect rinsing result. Go new ways. Set standards in the market and inspire customers. At the next time, we are looking for a Masterand (m/w/d) for our Development Hardware department for the duration of approximately 6 months.

The aim of this master thesis is to develop a compact, reliable measurement system for the quality determination of liquids in flushing systems, to carry out measurement series on different liquids and to develop data-driven methods for quality classification and correlation with reference parameters. Electrochemical impedance spectroscopy (EIS) makes it possible to measure the complex impedance of samples over a frequency range and to derive material- or quality-relevant properties therefrom. Conception and construction of an EIS measurement system (hardware and firmware) performing reproducible measurements on selected liquids under defined conditions Signal processing and extraction of relevant features (e.g., Nyquist/ Bode parameters, replacement circuit diagram situations) Development and evaluation of algorithms for quality assessment/classification and correlation analyses with reference variables (e.g. conductivity, pH, temperature) Methodological documentation, validation of the approach and critical classification of the limits of measurement methodology

You are a enrolled student (m/w/d) in a master's program in the field of electrical engineering, information technology, embedded systems, mechatronics or comparable You have well-founded knowledge of analog/digital measurement technology and signal processing Experience in embedded programming (e.g. C/C++ on STM32/ ESP32 or similar) If you have basic knowledge of data analysis/ML (e.g. Python, or similar), this is advantageous The safe handling of laboratory equipment (oscilloscope, function generator, LCR/ impedance measurement) is of course for you You have a structured, independent way of working and enjoy experimental validation You bring very good knowledge of German and good knowledge of English New ways to go. Make the market. Customers inspire. .
