YANG Ying, CHEN Xiang-dong, CAI Bin. Development of sensor’s film structure and analysis of response time[J]. 2009, 28(5): 52-54. DOI: 10.13873/j.1000-97872009.05.038.
A new film structure model of gas sensor with three-dimensional sensitive effect is provided
which is improving the traditional planar structure of uniform thickness to the new sensitive three-dimensional structure with more half-cylinder uplifts and more grooves.According to the proliferation response theory
the film sensor response times of both new and traditional structure sensor are analyzed and compared.This proves that the response time of the sensor with the new sensitive structure is short.And the influence of the half-cylinder bulges spacing relative coefficient on the sensor response time is analyzed
the best value is obtained.
