Resistance Pressure Sensor Based on Ag/Cu₂O-PEPC-NiPc/Al Composite

Abstract:

This work reports on the fabrication and investigation of pressure sensor based on Ag/Cu₂O-PEPC-NiPc/Al composite. The active layer of the composite was deposited by drop-casting of the blend Cu₂O-PEPC-NiPc on flexible substrate. The thin film of the blend consist of cuprous oxide (Cu₂O) micropowder, (5 wt. %), poly-N-epoxypropylcarbazole (PEPC), (2 wt. %) and nickel phthalocyanine (NiPc) micropowder, (3 wt. %) in benzol (1 ml). The film thickness of the composite is in the range of 20-30 μm. It is found that the fabricated sensor is sensitive to pressure and showed good repeatability. The decrease in resistance of the sensor is observed 10 times by increasing the external uniaxial pressure up to 11.7 kNm^-2. The experimentally obtained results are compared with the simulated results and showed reasonable agreement with each other.
