| Abstract: | The copolymer sensitive to humidity is obtained by graft polymerization reaction. The resistance-type humidity sensor based on the copolymer material has been fabricated. The impedance of the humidity sensor forms three orders of magnitude when humidity changes from low to high,with the response time not excessing 5 second. We have also tested humidity sensing characteristic, voltage characteristic, frequency characteristic, temperature characteristic and altering current properties. The sensing mechanism has been discussed as well in this papre. |
