Paper Abstract

Nafion® is well known copolymer from DuPont that is used as a material for membrane in fuel cells. It is also known as sensing component in different gas and humidity sensors[1]. This copolymer was used to humidity sensor fabrication. Proposed sensor is build as thin layer of Nafion® copolymer dipped on quartz resonator making mikrobalance scale. In this work we present a sensor responses in change of its resonance frequency due to the humidity change from 20% to 80% of RH. The sensor frequency is measured in microprocessor controlled environment to maintain faster response of the sensor. Sensed gas temperature must be measured to compensate temperature drift.
