Abstract With a view toward the application of highly hygroscopic polymers as humidity responsive self-actuator, evaluation real time moisture concentration in material becomes priority. In this paper, diffusion process cellulose acetate (53.3% acetylation) has been studied. Membranes (thickness within range 66–200 µm) have prepared, and absorption at room temperature different relative (RH 21–...

This paper presents a highly sensitive differential soil moisture sensor (DSMS) using microstrip line loaded with triangular two-turn resonator (T2-SR) and complementary of the rectangular spiral (CR2-SR), simultaneously. Volumetric Water Content (VWC) or permittivity sensing is conducted by loading T2-SR side dielectric samples. Two transmission notches are observed for identical loads relatin...
