Abstract
A sensor element () includes a first conductive electrode () having a first conductive member () electrically coupled thereto; an absorptive dielectric layer () comprising a polymer of intrinsic microporosity; and a second conductive electrode () having a second conductive member () electrically coupled thereto. The second conductive electrode comprises carbon nanotubes and is permeable to at least one organic vapor. The absorptive dielectric layer is at least partially disposed between the first conductive electrode and the second conductive electrode. A method of making the sensor element, and sensor device () containing it, are also disclosed.
