Mass sensitivity is a key parameter to characterize its performance. In this work, the effects of mass load distribution on the mass sensitivity of a magnetoelastic sensor under different resonance modes were theoretically investigated using the modal analysis method. The results show that the mass sensitivity and \u201cnodal point\u201d positions are related to the point displacement, which is determined by the motion patterns. The motion patterns are affected by resonance modes and mass load distribution. Asymmetrical mass load distribution causes the motion patterns lose symmetry and leads to the shift of \u201cnodal point\u201d. The mass sensitivity changing with mass load distribution behaves like a sine wave with decaying amplitude and the minimum  mass sensitivity appears at the first valley. This study provides certain theoretical  guidance for optimizing the mass sensitivity of a magnetoelastic sensor or other acoustic wave based sensors.<\/jats:p>","DOI":"10.3390\/s150820267","type":"journal-article","created":{"date-parts":[[2015,8,18]],"date-time":"2015-08-18T05:43:13Z","timestamp":1439876593000},"page":"20267-20278","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Mass Load Distribution Dependence of Mass Sensitivity of Magnetoelastic Sensors under Different Resonance Modes"],"prefix":"10.3390","volume":"15","author":[{"given":"Kewei","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}]},{"given":"Lin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Materials Research and Education Center, Auburn University, Auburn, AL 36849, USA"}]},{"given":"Yuesheng","family":"Chai","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"294","DOI":"10.3390\/s20700294","article-title":"Wireless magnetoelastic resonance sensors: A critical review","volume":"2","author":"Grimes","year":"2002","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1016\/j.sna.2012.12.013","article-title":"Magnetostrictive resonators as sensors and actuators","volume":"200","author":"Zhang","year":"2013","journal-title":"Sens.
