    摘要: A vapor sensor includes a capacitance-related property sensor element (110), a heater circuit element (170), a capacitance-related property measurement circuit element (180), and at least one switch member (190). The capacitance-related property sensor element includes a dielectric substrate (120), a first conductive electrode (130), a second conductive electrode (140), and a layer of dielectric microporous material (150) disposed between and contacting the first conductive electrode and the second conductive electrode. The at least one switch member is capable of interrupting electrical communication between the first conductive electrode and the heater circuit element, and between the capacitance-related property measurement circuit element and the first conductive electrode.
