| 摘要 |
A humidity sensor includes a substrate, at least two elongated electrodes formed respectively on the substrate where each of the elongated electrodes has a first end and a second end, at least a pair of comb-like electrodes each contacting with the first end of the elongated electrode, and a humidity sensitive film which contains hydrophilic ionic polymer and is formed respectively on the at least a pair of comb-like electrodes but not on the second ends of the elongated electrodes. In addition, the present invention further comprises a method for making such a humidity sensor.
