发明名称 Humidity-sensitive element
摘要 PCT No. PCT/JP81/00166 Sec. 371 Date Mar. 18, 1982 Sec. 102(e) Date Mar. 18, 1982 PCT Filed Jul. 20, 1981 PCT Pub. No. WO82/00362 PCT Pub. Date Feb. 4, 1982.The humidity-sensitive element of this invention is composed of an insulating substrate (1), a pair of electrodes (2, 3) mounted thereon, and a humidity-sensitive material (8) covering the electrodes. The humidity-sensitive material (8) has a property to change its electric resistance depending on the moisture content in the atmosphere and is formed from fine particles each having a hydrophobic core and a hydrophilic group-containing surface layer covering the core. This humidity-sensitive element exhibits a nearly linear relationship between logarithum of electric resistance and relative humidity and small hysteresis, permitting a precise measurement of relative humidity. Insulating substrate (1) and electrodes (2,3) are preferred to form from an insulating layer of silicon semiconductor and conductive monosilicon formed on it, respectively. This permits size reduction of humidity-sensitive elements or devices.
