EXTENDED ABSTRACT: Metal oxide (MOX) gas sensor (MOS) with the characteristics of low cost, simplicity of integration and large number of detectable gases/possible application fields, is one of the most promising candidates for gas sensors. MOX films are the critical part of the MOS. However, there are still some shortcomings to be addressed urgently, for instance, poor selectivity and instability at high temperature. Therefore, in order to obtain excellent performance, stable and good resistance type gas sensitive films, we tested the properties of all possible materials in definite range through parallel synthesis and high-throughput characterization, so that effective experimental scheme could be concluded to select the suitable type of gas sensitive material, from the regular pattern. Meanwhile, we have designed a combination material screening platform for, including a parallel synthesizing instruments and a high throughput characterization equipment for gas-sensing films. The platform has the characteristics of automatic parallel synthesis, material adaptability, wide range proportion regulation, high throughput characterization, screening materials with short cycles and high efficiency. And it is a promising solution for obtaining high performance gas-sensing materials and gas sensors, and realizing fast and accurate odor detection.
