We calculate the transmittance spectrum and the electromagnetic field distribution using the finite element method. When the resonator\u2019s top layer undergoes pressure, the resonance wavelength redshifts with increasing deformation, and their relation is nearly linear. The designed pressure sensor possesses the merits of ultrahigh sensitivity, multiple modes, and a simple structure. The maximum sensitivity and resonance wavelength shift can achieve 592.44 nm\/MPa and 364 nm, respectively, which are the highest values to our knowledge. The obtained sensitivity shows 23.32 times compared to the highest one reported in the literature. The modeled design paves a promising path for applications in the nanophotonic field.<\/jats:p>","DOI":"10.3390\/nano11113147","type":"journal-article","created":{"date-parts":[[2021,11,21]],"date-time":"2021-11-21T21:00:50Z","timestamp":1637528450000},"page":"3147","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Ultrahigh Sensitivity of a Plasmonic Pressure Sensor with a Compact Size"],"prefix":"10.3390","volume":"11","author":[{"given":"Chung-Ting","family":"Chou Chao","sequence":"first","affiliation":[{"name":"Department of Optoelectronics and Materials Technology, National Taiwan Ocean University, Keelung 20224, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5249-8715","authenticated-orcid":false,"given":"Yuan-Fong","family":"Chou Chau","sequence":"additional","affiliation":[{"name":"Centre for Advanced Material and Energy Sciences, Universiti Brunei Darussalam, Tungku Link, Gadong, Bandar Seri Begawan BE1410, Brunei"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sy-Hann","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Electrophysics, National Chiayi University, Chiayi 600, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3753-0067","authenticated-orcid":false,"given":"Hung Ji","family":"Huang","sequence":"additional","affiliation":[{"name":"National Applied Research Laboratories, Taiwan Instrument Research Institute, Hsinchu 300, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chee Ming","family":"Lim","sequence":"additional","affiliation":[{"name":"Centre for Advanced Material and Energy Sciences, Universiti Brunei Darussalam, Tungku Link, Gadong, Bandar Seri Begawan BE1410, Brunei"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7974-3162","authenticated-orcid":false,"given":"Muhammad Raziq Rahimi","family":"Kooh","sequence":"additional","affiliation":[{"name":"Centre for Advanced Material and Energy Sciences, Universiti Brunei Darussalam, Tungku Link, Gadong, Bandar Seri Begawan BE1410, Brunei"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7931-199X","authenticated-orcid":false,"given":"Roshan","family":"Thotagamuge","sequence":"additional","affiliation":[{"name":"Centre for Advanced Material and Energy Sciences, Universiti Brunei Darussalam, Tungku Link, Gadong, Bandar Seri Begawan BE1410, Brunei"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0752-175X","authenticated-orcid":false,"given":"Hai-Pang","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Optoelectronics and Materials Technology, National Taiwan Ocean University, Keelung 20224, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113001","DOI":"10.1088\/0022-3727\/45\/11\/113001","article-title":"Surface plasmon polaritons: Physics and applications","volume":"45","author":"Zhang","year":"2012","journal-title":"J.
