“…The cost fraction could be substantially reduced in the conventional Si-chip devices by replacing the existing thermistor with a printed thermistor and bridging the Si-chip with an R2R-printed circuit. 23 Naturally, the PEDOT:PSS ink employed herein to realize the printed thermistor is R2R printable and can offer a fully gravure-printed sensor device in the future. In fact, recent studies have successfully demonstrated the printability of PEDOT:PSS as a transparent electrode material via screen 5 and inkjet 27 printing.…”

“…The average linear resolution, a metric for examining the signalto-noise ratio, of the thermistor (DR/DT) was found to be 1272.57 U per C, which was 50 times that of the reported hydrophobic silver nanoparticle-based thermistor exhibiting a positive thermal coefficient. 23 Furthermore, the temperature coefficient of resistance (calculated at T ¼ 25 C) of the proposed FGO-PEDOT thermistors was found to be À3.95 Â 10 À3 per C. This linearity of the thermistor during cyclic measurements ensures that the proposed FGO-PVDF encapsulation layer is highly efficient to circumvent the effect of humidity because there will be periodic formation of ice- liquid-vapor states of water molecules on the inner surface of the glass jacket as a result of temperature variation. We evaluated the stability of the thermistor (Fig.…”

“…Thermocouples can be inaccurate if exposed to moisture, voltage noise, or large variations in ambient temperature, whereas RTDs are expensive and rarely used in cold chain logistics [19,20]. Due to good accuracy and small size [21][22][23][24], many temperature-tracking systems prefer thermistors, but those allowing high accuracy measurements are expensive, fragile and need filters or DC voltage because of their high resistance [25]. In recent years, other techniques have been investigated to measure temperature in cold chain products, e.g.…”
