摘要

采用微热平台(MHP)和单层有序多孔SnO2纳米膜融合的新型微纳气体传感器，实现了低功耗、高灵敏度和快速响应的超高性能。基于基于铂微加热器和数字间电极(IDE)的MHP，采用聚苯乙烯球单层胶体晶体模板原位合成了高度有序的SnO2多孔膜。测试结果表明，该传感器对100 ppb乙醇敏感，灵敏度为1.6 (Rair/Rgas)，功耗为25 mW，响应时间小于2 s。传感器的检出限计算为9 ppb。

Ultra high performance gas sensor based on IC compatible fusion of micromachined hotplatform and nanostructured porous film

Ultra-high performances of low power, high sensitivity, and fast response was achieved in a novel micro/nano gas sensor that fused a microhotplatform (MHP) and a monolayer of ordered porous SnO2 nanofilm. Based on the MHP with a platinum microheater and interdigital electrode (IDE), a highly ordered SnO2 porous film was in-situ synthesized using a polystyrene sphere monolayer colloidal crystal template. Test results indicated that the sensor was sensitive to 100 ppb ethanol with a sensitivity of 1.6 (Rair/Rgas), a power consumption of 25 mW and a response time less than 2 s. The detection limit of the sensor was calculated as 9 ppb.
