Abstract

Simple optic sensors for detecting fuel gases, which consist of plastic optical fibers (POFs), have been studied. The sensing mechanism is based on the swelling phenomena in the rubber-type polymers. The POF-type sensor head was fabricated by coating the swelling polymer on the plastic fiber core and was connected to the normal POFs. When this system was exposed to fuel gases such as gasoline and propane, the light intensity passing through the sensor head changed remarkably depending on the pressure of fuel gases. The sensor response was also found to be fast, stable and reproducible.
