Fabrication of the sensors was carried out at 1050 \u00b0C in order to establish a porous YSZ electrolyte that enabled gas diffusion. Two electrode configurations were studied where Au wire electrodes were either embedded within or wrapped around the YSZ electrolyte. The electrical response of the sensors was collected via impedance spectroscopy under various operating conditions where gas concentrations ranged from 0 to 100 ppm NO and 1%\u201318% O2 at temperatures varying from 600 to 700 \u00b0C. Gas diffusion appeared to be a rate-limiting mechanism in sensors where the electrode configuration resulted in longer diffusion pathways. The temperature dependence of the NO sensors studied was independent of the electrode configuration. Analysis of the impedance data, along with equivalent circuit modeling indicated the electrode configuration of the sensor effected gas and ionic transport pathways, capacitance behavior, and NO sensitivity.<\/jats:p>","DOI":"10.3390\/s150924573","type":"journal-article","created":{"date-parts":[[2015,9,23]],"date-time":"2015-09-23T12:24:25Z","timestamp":1443011065000},"page":"24573-24584","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of Electrode Configuration on Nitric Oxide Gas  Sensor Behavior"],"prefix":"10.3390","volume":"15","author":[{"given":"Ling","family":"Cui","sequence":"first","affiliation":[{"name":"Institute for Micromanufacturing, Louisiana Tech University, Ruston, LA 71272, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erica","family":"Murray","sequence":"additional","affiliation":[{"name":"Institute for Micromanufacturing, Louisiana Tech University, Ruston, LA 71272, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1038\/sj.jea.7500442","article-title":"Nitrogen dioxide prediction in Southern California using land use regression modeling: Potential for environmental health analyses","volume":"16","author":"Ross","year":"2006","journal-title":"J.
