本文报道了与气味产生系统耦合的人工嗅觉系统。人工嗅觉系统由四个化学传感器组成，这些传感器由涂有室温离子液体（RTIL）的石英晶体微天平（QCM）组成。传感器由四个矢量网络分析仪进行询问，用于测量串联谐振频率和运动电阻。气味发生系统可以产生八种不同的气味，并将它们混合成任意成分。电磁阀用于在混合前切换路径并控制不同气味的浓度。研究、优化和比较了控制电磁阀、Δ-Σ 调制器和简单脉宽调制 (PWM) 的两种算法。最后，计算臭味发生系统的不确定性。
An artificial olfactory system coupled with an odor generation system is herein reported. The artificial olfactory system is composed of four chemical sensors consisting of quartz crystal microbalances (QCMs) coated with room temperature ionic liquids (RTILs). The sensors are interrogated by four vector network analyzers, which are used to measure the series resonant frequency and motional resistance. The odor generation system can generate eight different odors and mix them in any composition. Solenoid valves are used to switch the path and control the concentration of the different odors before blending. Two algorithms to control the solenoid valves, delta-sigma modulator, and simple pulse width modulation (PWM) are studied, optimized, and compared. Finally, the uncertainty of the odor generating system is calculated.
