摘要：

The sensitivity to relative humidity of a sensor based on I-2-doped polyphenylacetylene thin film membranes has been investigated. The sensor geometry allows its application in miniature devices. The response to humidity variations (20%-80%) is fast and reproducible for long times (months). The I/V characteristics suggest that ionic type conductivity is prevailing. Current intensity measurements performed on films of different thicknesses show that surface conductivity is mainly responsible for the sensor's electrical response.
