薄膜電容濕度傳感器結構:
Upper electrode 上層電極
• conductive material 傳導材料
• protects the active material of the sensor from dust, dirt and conductive particles 保護傳感器的主要材料不受灰塵 , 污垢和導電粒子 的影響
• lets through water vapor 使水蒸汽通過 • functions as one of the two electrodes in a capacitor 做為電容兩極中 的一極
Active material 活性材料
• active polymer film 活性聚合物薄膜
• absorbs water vapor: amount is a function of ambient relative humidity 吸收水蒸汽 : 吸收量和周圍環境的相對濕度有函數關系 Lower electrode 下層電極
• made of conductive material 由傳導材料做成 • functions as one of the two electrodes in a capacitor 做為電容兩極中 的一極 Glass substrate 玻璃基底
• base that supports the sensor structure 支撐傳感器結構
