<P>PROBLEM TO BE SOLVED: To provide a simple and disposable humidity and temperature sensor, capable of easily acquiring the internal humidity/temperature state from the outside by the naked eye by inputting the sensor into a food packaging bag or the like, to achieve quality control of a small amount of unit of product, capable of discriminating simply a temperature and a humidification degree inside a polyelectrolyte film during operation of a solid polymer type fuel cell, and capable of being installed in an optional space; and to provide a simple temperature/humidity sensor utilizing a phenomenon wherein a crosslinkable resin composition acquired by subjecting a crosslinkable hydrocarbon-type polyelectrolyte film or a molded body to ion exchange by various alkali, alkaline earth or transition metal ions changes a color tone reversibly by the humidity or the temperature of an environment. <P>SOLUTION: In this temperature/humidity sensor, a molded body acquired by replacing H<SP>+</SP>ions in the crosslinkable resin composition acquired from poly-2-acrylamide-2-methylpropane sulfonic acid (PAMPS), polyvinyl alcohol (PVA) and a water-soluble polymer with various metal ions is used as a sensor element. <P>COPYRIGHT: (C)2008,JPO&INPIT |
