It is important that measurement systems provide an accurate and robust performance over a wide range of input conditions. Under these conditions, the measurement system is said to have a robust design with dynamic characteristics. This paper adopts Taguchi's signal-to-noise ratio analysis to optimize the dynamic characteristics of a piezoelectric gas sensor system whose output response is linearly related to the input signal. The goal of the present dynamic characteristics study is to increase the sensitivity of the measurement system while simultaneously reducing its variability. This study focuses upon the conventional quartz crystal nanobalance (QCN) gas sensor. A time- and cost-efficient finite element analysis method is utilized to investigate the effects of the deposited mass upon the resonant frequency output of the QCN biosensor.
测量系统在广泛的输入条件下提供准确且稳健的性能非常重要。在这些条件下，测量系统被认为具有具有动态特性的稳健设计。本文采用田口信噪比分析来优化压电气体传感器系统的动态特性，该系统的输出响应与输入信号呈线性相关。当前动态特性研究的目标是提高测量系统的灵敏度，同时降低其变异性。本研究聚焦于传统的石英晶体微天平（QCN）气体传感器。利用一种省时且经济高效的有限元分析方法来研究沉积质量对QCN生物传感器谐振频率输出的影响。
