With the variation of the environment, the requirements of anti-interference, miniaturization, and ultra-sensitivity are put forward. Optical microcavities are often carefully designed for a variety of ultra-sensitive detections. Using the packaged microsphere cavity, we fabricated an ultrasound sensor that can work in an underwater environment. During practical detection, the optical resonance mode of the cavity can work with real-time response accordingly. The designed structure can work in various complex environments and has advantages in the fields of precision measurement and nano-particle detection.<\/jats:p>","DOI":"10.3390\/s22114190","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T09:24:29Z","timestamp":1653989069000},"page":"4190","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Ultrasound Sensing Using Packaged Microsphere Cavity in the Underwater Environment"],"prefix":"10.3390","volume":"22","author":[{"given":"Kai","family":"Wang","sequence":"first","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China"},{"name":"The State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China"},{"name":"The State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xing-Yu","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China"},{"name":"The State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6758-5718","authenticated-orcid":false,"given":"Yong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China"},{"name":"The State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1976-8821","authenticated-orcid":false,"given":"Daquan","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongzhen","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China"},{"name":"The State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0466-3165","authenticated-orcid":false,"given":"Chuan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Beijing Normal University, Beijing 100875, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1093","DOI":"10.1021\/ph500159g","article-title":"Ultrabroad Bandwidth and Highly Sensitive Optical Ultrasonic Detector for Photoacoustic Imaging","volume":"1","author":"Zhang","year":"2014","journal-title":"ACS Photonics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1038\/nrd1662","article-title":"Healing sound: The use of ultrasound in drug delivery and other therapeutic applications","volume":"4","author":"Mitragotri","year":"2005","journal-title":"Nat.
