提出了一种基于陶瓷气敏元件非线性动态响应信息的气敏新方法。将正弦电压施加到配备有SnO2气体传感器的加热器上，并通过快速傅立叶变换（FFT）分析所得的输出电阻。结果发现，高次谐波的强度表现出相对于不同种类的气体的特征变化。
A novel method of gas-sensing is proposed based on the information of nonlinear, dynamic response of a ceramic gas sensor. A sinusoidal voltage is applied to a heater equipped with a SnO2 gas sensor and the resulting output resistance is analyzed by the Fast Fourier Transformation (FFT). It was found that the intensities of the higher harmonics exhibit characteristic changes with respect to different kind of gas.
