Project description

The main objective of the project is to establish a rapid, non-destructive ex-ante method for predicting the long-term stability and drift of cryogenic temperature sensors. Present stability verification relies on lengthy, expensive post-facto calibrations, as the link between microstructural defects and sensor aging remains unverified with other methods. This project addresses this limitation by investigating the complex electrical response of Pt100/Pt1000 sensors and capsule-type SPRTs across various aging protocols, including rapid cryogenic thermal cycling and prolonged continuous operation.

By combining non-linear current-voltage (AC/DC) characterization with wide-temperature Electrical Impedance Spectroscopy (EIS), the research aims to identify a unique electrical signature - stemming from grain boundaries, impurities, and contact dynamics - that correlates directly with long-term drift. Ultimately, the project will equip precision thermometry with a diagnostic framework to forecast sensor reliability within hours rather than months, advancing the development of next-generation temperature sensors.
