Characterization of embedded temperature sensors on QCM in cryogenic environment

This work deals with the temperature characterization of embedded resistors deposited on a quartz crystal microbalance developed for thermogravimetric analyses in Space, i.e. the Contamination Assessment Microbalance project. The instrument allows in-situ thermogravimetric analyses thanks to the deposited resistors on the quartz crystals. Developed technology would improve the thermal control of the microbalance, but linearity of the deposited materials within the expected temperature range is of primary importance to provide accurate temperature measurement and get reliable results from the instrument thermogravimetric analyses. Thus, linearity of the Cr-Au material has been assessed down to cryogenic temperatures, lowest limit of the intended application.
