Characterization of Printed Thermistors

This paper deals with the characterization of printed thermistors based on metallic oxides. In total, three different thermosensitive printing formulations were tested. Formulations differed in the mechanical properties of a polymeric binder. The long-term stability, calibration curves, hysteresis, and effects of environments with different relative humidity were measured. Measurements were done in controlled environments inside the climatic chamber and laboratory hot air oven. The results show that the formulation with a hard polymeric binder is stable and perform well under tested conditions.
