Abstract

In this study, V"2O"4-PEPC based pressure sensor was designed and fabricated by drop-casting the blend of V"2O"4-PEPC microcomposite thin films of vanadium oxide (V"2O"4) micropowder (10wt.%) and poly-N-epoxypropylcarbazole, PEPC (2wt.%) in benzol (1ml) on steel substrates. The thickness of the V"2O"4-PEPC films was in the range of 20-40@mm. The DC resistance of the sensor was decreased in average by 24 times as the pressure was increased up to 11.7kNm^-^2. The resistance-pressure relationships were simulated.
