Sensitive characteristics of ZnO nano gas sensor based on dynamic temperature modulation

摘要

In this paper, nano ZnO gas sensing materials and sensors are designed and fabricated by hydrothermal method. Focus on the selectivity problem of metal oxide gas sensors, a novel dynamic temperature modulation test method is proposed, and six quintessential VOCs gas response characteristics are investigated based on the optimized trapezoidal wave. The results can propose a technical basis for the accurate sensing device at the front of the artificial intelligence industry.
