Abstract :
In this study V2O4-PEPC composite based temperature sensors were designed and fabricated by drop-casting the blend of V2O4-PEPC microcomposite into thin films between the gap of preliminary deposited electrodes on a glass substrates. The blend was prepared by mixing 10 wt.% vanadium oxide (V2O4) micro-powder and 2 wt.% poly-N-epoxypropylcarbazole (PEPC) in 1 ml of benzol. The thickness of the V2O4-PEPC films was in the range of 20-40 μm. The gap between silver electrodes was in the range 30-40 μm. The length of silver electrodes was equal to 15 mm. It was found that with increase in temperature from 33 °C to 90 °C the AC resistance of the samples decreases by 10-12 times. The resistance-temperature relationships were simulated.
