Abdul Quddious, et al., " Disposable, paper-based, inkjet-printed humidity and H2S gas sensor for passive sensing applications" . Sensors, 16 (12), 2016, 2073. An inkjet-printed, fully passive sensor capable of either humidity or gas sensing is presented herein. The sensor is composed of an interdigitated electrode, a customized printable gas sensitive ink and a specialized dipole antenna for wireless sensing. The interdigitated electrode printed on a paper substrate provides the base conductivity that varies during the sensing process. Aided by the porous nature of the substrate, a change in
