To cite an example, electronic noses have recently been a hot item in the United States and Europe. One of their functions is to select the best roses for turning into perfume. There are also electronic tongues that can taste (or actually smell) if food has salmonella.
舉一個例子，最近歐美甚為熱門、內含多個感測元件的「電子鼻」，功能之一是可以選擇頂級玫瑰提煉香水；還有「電子舌」，可以辨嗅出食物中是否暗藏沙門氏桿菌。
