Abstract
Polydimethylphosphazene (PDMP) has been tested for the first time to f abricate a water resistive humidity sensor. The device consists of a P DMP free-standing membrane coated on both sides with gold electrodes f orming a parallel capacitor. A change in electrical capacitance and re sistance of about three orders of magnitude was observed with increasi ng relative humidity (RH) from 0% to 100%. The results show that polyp hosphazenes are promising materials for resistive and capacitive senso rs in the complete range of RH.
