The Pd-Ni thin-film was sputtered onto the SAW propagation path of a SAW device with a delay line pattern to build the chip-sized hydrogen sensor. The prepared sensor chip was characterized by employing a differential oscillation loop. The effect of the Pd-Ni film thickness on sensing performance was also evaluated, and optimal parameters were determined, allowing for fast response and high sensitivity. Excellent working stability (detection error of 3.7% in half a year), high sensitivity (21.3 kHz\/%), and fast response (less than 10 s) were achieved from the 40 nm Pd-Ni alloy thin-film coated sensing device.<\/jats:p>","DOI":"10.3390\/s19163560","type":"journal-article","created":{"date-parts":[[2019,8,15]],"date-time":"2019-08-15T11:11:00Z","timestamp":1565867460000},"page":"3560","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Development of a High Stability Pd-Ni Alloy Thin-Film Coated SAW Device for Sensing Hydrogen"],"prefix":"10.3390","volume":"19","author":[{"given":"Wen","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Non-Destructive Testing Ministry of Education, Nanchang HangKong University, Nanchang 330063, China"},{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueli","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"},{"name":"School of Electronic, Electrical and Communication Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengchao","family":"Mei","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengwei","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Lu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Non-Destructive Testing Ministry of Education, Nanchang HangKong University, Nanchang 330063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minghui","family":"Lu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Non-Destructive Testing Ministry of Education, Nanchang HangKong University, Nanchang 330063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, W., Guo, Y., Tang, Y., Zu, X., Ma, J., Wang, L., and Fu, Y.Q.
