Abstract

The development of a low level humidity capacitive sensing device working at room temperature, based on a thick layer of iron oxide nanopowders dispersed into a poly(diallyldimethylammoniumchloride) (PDDAC) hydrophilic host matrix deposited on flexible commercial plastic substrates provided with silver electrodes, is reported. The sensor response was tested in a transduction system based on a capacity-frequency conversion of the timing circuit by means of a microcontroller unit. The sensor was investigated in the absolute humidity range from 0% to 1%, showing a good sensitivity and response linearity.
