    • Gas sensors are described herein that are useful for selectively detecting a second gas (e.g. isoprene) in the presence of a first gas (e.g. acetone). The gas sensors include a sensor element which includes a semiconductor sensing material and a porous material. The sensor element is configured so that the porous material absorbs more of the first gas than the second gas. Thus, when the gas being analyzed, such as a mammalian (including human) breath, a greater proportion of the second gas comes into contact with the semiconductor sensing material.
    • 本文描述了在第一气体(例如丙酮)存在下有选择地检测第二气体(例如异戊二烯)的气体传感器。 气体传感器包括传感器元件,其包括半导体感测材料和多孔材料。 传感器元件被构造成使得多孔材料比第二气体吸收更多的第一气​​体。 因此,当被分析的气体,例如哺乳动物(包括人)呼吸时,较大比例的第二气体与半导体感测材料接触。
