摘要：

The fabrication of a relative humidity sensor in which the principle of operation is based on the change of dielectric constant of a polyethylenterephthalate (PETT) film is studied. The linearity, response time in sorption process, stability and effect of the temperature in the new sensor are given. A qualitative chemical sensing mechanism is presented. The results, allow the use of the device in instruments and systems for moisture measurements. (C) 1997 Published by Elsevier Science S.A.
