Highly sensitive and selective surface acoustic wave ammonia sensor operated at room temperature with a polyacrylic acid sensing layer

HIGHLIGHTS

  • who: Weiqiang Wang et al. from the School of Physics, University of Electronic Science and Technology of China, Chengdu, China have published the article: Highly Sensitive and Selective Surface Acoustic Wave Ammonia Sensor Operated at Room Temperature with a Polyacrylic Acid Sensing Layer, in the Journal: Sensors 2022, 22, 6349. of /2022/
  • what: In this work, a PAA-based ammonia SAW sensor was made on an ST cut quartz substrate, and its ammonia-sensing mechanism operated at room temperature was studied. Clearly, the SAW sensor with the PAA layer in this study showed one of . . .
