Fig. 4: Performance of a textile-type dual-threshold logic switch circuit, formed by interweaving fiber-type humidity sensors together with one fiber section composed of two circuit units.
From: Smart fiber with overprinted patterns to function as chip-like multi-threshold logic switch circuit
a Schematic diagram of the textile-type dual-threshold logic switch circuit. b Structure of the fiber-type humidity sensor. (Inset: SEM image of PVA/SWCNT layer). c Working principle of the fiber-type humidity sensor. d FTIR spectra of the PVA/SWCNT layer under dry and swollen conditions. e Performance of the fiber-type humidity sensor under different humidity (RH%). f Repeatability of the fiber-type humidity sensor. g Resistance of fiber-type humidity sensor under different bending times. h, i Characteristics of the textile-type dual-threshold logic switch circuit under different humidity.
