【 摘 要 】

In this communicationwe describe the application of a conductive polymer gas sensor as an air pressuresensor. The device consists of a thin doped poly(4'-hexyloxy-2,5-biphenyleneethylene) (PHBPE) film deposited on an interdigitated metallic electrode. Thesensor is cheap, easy to fabricate, lasts for several months, and is suitablefor measuring air pressures in the range between 100 and 700 mmHg.
