Abstract
A device for surface acoustic wave (SAW) measurements, based on a poly meric sensitive membrane, that is polyethynylfluorenol (PEFl), has bee n realized. The SAW/PEFl sensor shows relatively fast and highly sensi tive responses in the range of relative humidity 0-60%. The enhanced s ensitivity of the SAW/PEFl device, in comparison with that of a SAW se nsor which utilized a polyphenylacetylene film, may be attributed to t he presence of OH groups belonging to the polymer repeat unit.
