Fabrication, Performances and Aging of Flexible Gas Sensor Platforms Medina Rodríguez, Beatriz Vescio, Giovanni Arrese, Javier Varea Espelt, Aïda Ramos, Francisco Cirera Hernández, Albert Serigrafia Electrònica Detectors de gasos Serigraphy Electronics Gas detectors Flexible electronics are attracting much interest in gas sensor field on on-site monitoring applications due to their wear ability, lightweight and low-cost production. These performances are fully accomplished by silver-based platforms, but silver corrosion represents the main drawback for the integrity of the devices. In this work, self-heating sensor platforms fabricated by screen- and inkjet-printing techniques have been developed. The reliability of both types of sensors has been tested by long-term lifetime characterization and aging tests. These tests proved that the actuation time is interrupted by silver corrosion phenomena in screen-printing devices and by hot spots in inkjet-printing ones. Appropriate solutions regarding isolation and design improvements achieved not only an increase of lifetime and reliability, but also a decrease of power consumption. 2018-05-29T10:32:04Z 2018-05-29T10:32:04Z 2015 2018-05-29T10:32:04Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.17265/2161-6221/2015.3-4.009 Journal of Materials Science and Engineering B, 2015, vol. 5, num. 3-4, p. 170-176 https://doi.org/10.17265/2161-6221/2015.3-4.009 cc-by-nc (c) David Publishing, 2015 http://creativecommons.org/licenses/by-nc/3.0/es info:eu-repo/semantics/openAccess David Publishing Articles publicats en revistes (Enginyeria Electrònica i Biomèdica)
