In this paper the development of a measurement setup for resistive films able to perform sensing tests within a wide resistance range is reported. The system is fully automated, allowing to perform time-consuming sensing tests without operator supervision. Here, a thick film planar-type sensor was investigated. Cu-doped SnO2 was used as sensing element deposited by screen printing on the planar ceramic substrate provided with Pt interdigited contacts. First results showed a predictable behavior vs. low values of humidity and a satisfactory attitude to thermal stress. The system is a promising tool both in sensing performance film evaluation and in device prototype characterization. © 2014 Springer International Publishing Switzerland.

Abstract
In this paper the development of a measurement setup for resistive films able to perform sensing tests within a wide resistance range is reported. The system is fully automated, allowing to perform time-consuming sensing tests without operator supervision. Here, a thick film planar-type sensor was investigated. Cu-doped SnO2 was used as sensing element deposited by screen printing on the planar ceramic substrate provided with Pt interdigited contacts. First results showed a predictable behavior vs. low values of humidity and a satisfactory attitude to thermal stress. The system is a promising tool both in sensing performance film evaluation and in device prototype characterization. © 2014 Springer International Publishing Switzerland.Pubblicazioni consigliate
