Herein, we reported the fabrication of ferroelectric barium strontium titanate ((Ba70Sr30)TiO3, BST) thin films on silicon substrates by magnetron sputtering. The as-grown BST films have a pure perovskite structure and exhibit excellent ferroelectric characteristics, such as a remnant polarization of 2.4 \u03bcC\/cm2, a ferro-to-paraelectric (tetragonal-to-cubic) phase transition temperature of 31.2 \u00b0C, and a broad optical bandgap of 3.58 eV. Capacitor-based sensors made from the BST films have shown an outstanding average sensitivity of 0.10\u2009mV\u00b7Pa\u22121 in the 10\u201380\u2009kPa regime and work extremely steadily over 1000 cycles. More importantly, utilizing the Pockels effect, optical manipulation in BST can be also realized by a smaller bias and its electro-optic coefficient reff is estimated to be 83.5 pmV\u22121, which is 2.6 times larger than in the current standard material (LiNbO3) for electro-optical devices. Our work established BST thin film as a powerful design paradigm toward on-chip integrations with diverse electronics into sensors via CMOS-comparable technique.<\/jats:p>","DOI":"10.3390\/s22197183","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T23:07:55Z","timestamp":1663888075000},"page":"7183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Smart Sensing Multifunctionalities Based on Barium Strontium Titanate Thin Films"],"prefix":"10.3390","volume":"22","author":[{"given":"Linghua","family":"Wang","sequence":"first","affiliation":[{"name":"College of Physics and Information Engineering, Fuzhou University, Fuzhou 350108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minmin","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Physics and Information Engineering, Fuzhou University, Fuzhou 350108, China"},{"name":"FZU-Jinjiang Joint Institute of Microelectronics, Jinjiang Science and Education Park, Fuzhou University, Jinjiang 362200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Shao","sequence":"additional","affiliation":[{"name":"FZU-Jinjiang Joint Institute of Microelectronics, Jinjiang Science and Education Park, Fuzhou University, Jinjiang 362200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yida","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Can","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Physics and Information Engineering, Fuzhou University, Fuzhou 350108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Langfeng","family":"Gao","sequence":"additional","affiliation":[{"name":"FZU-Jinjiang Joint Institute of Microelectronics, Jinjiang Science and Education Park, Fuzhou University, Jinjiang 362200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiping","family":"Bao","sequence":"additional","affiliation":[{"name":"Academy of Hi-Tech Research, Hunan Institute of Traffic Engineering, Hengyang 421099, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"314","DOI":"10.1038\/s41928-018-0071-7","article-title":"A Stretchable and Biodegradable Strain and Pressure Sensor for Orthopaedic Application","volume":"1","author":"Boutry","year":"2018","journal-title":"Nat.
