Development of Order Sensing System using Quartz-resonators

我们研制了一种用四个和六个石英谐振器涂上吸收膜的气味传感系统，并用这些系统对柑橘类水果进行了识别试验。从谐振频率的响应模式中，可以看出13种柑橘类水果（柚子、龙眼、土佐文旦、柠檬、葡萄柚等）之间的细微差别。可能会被歧视。通过蒸发有序样品，它能够在短的测量时间内以高灵敏度进行区分。对传感器阵列元件进行了优化设计，并对11种不同类型的传感膜进行了柑橘类水果的识别实验。分析了石英谐振器的响应模式，对优化的气味传感系统具有重要意义。利用六种瞬态响应曲线的梯度进行了神经网络模式识别分析，对八种柑橘类水果的识别率在80%以上。

We have developed odor sensing systems using the four and six quartz-resonators coated with absorption films, Recognition of citrus fruits with these systems was tried, From the response pattern of resonant frequency, fine difference among thirteen kinds of citrus fruits (Yuzu, lyokan, Tosa-buntan, lemon, grapefruits, etc.) could be discriminated. By vaporizing the order samples, it was able to discriminate with high sensitivity for a short measurement time. The optimization of the sensor-array components has been made, and for the recognition of citrus fruits, 11 kinds of membrane were tried, It is important to analyze the response pattern of quartz-resonators for the optimized odor sensing system. The pattern recognition analysis by neural network analysis was carried out using the gradient of six transient response curves, The recognition probability of this method for eight kinds of citrus fruits is more than 80%.
