A sensor made of diamond will be even more promising when combined with some advantages of optical sensing (i.e., EMI inertness, high temperature operation, and miniaturization). We present a miniature diamond-based fiber optic pressure sensor fabricated using dual polymer-ceramic adhesives. The UV curable polymer and the heat-curing ceramic adhesive are employed for easy and reliable optical fiber mounting. The usage of the two different adhesives considerably improves the manufacturability and linearity of the sensor, while significantly decreasing the error from the temperature cross-sensitivity. Experimental study shows that the sensor exhibits good linearity over a pressure range of 2.0\u20139.5 psi with a sensitivity of 18.5 nm\/psi (R2 = 0.9979). Around 275 \u00b0C of working temperature was achieved by using polymer\/ceramic dual adhesives. The sensor can benefit many fronts that require miniature, low-cost, and high-accuracy sensors including biomedical and industrial applications. With an added antioxidation layer on the diamond diaphragm, the sensor can also be applied for harsh environment applications due to the high melting temperature and Young\u2019s modulus of the material.<\/jats:p>","DOI":"10.3390\/s19092202","type":"journal-article","created":{"date-parts":[[2019,5,13]],"date-time":"2019-05-13T11:00:57Z","timestamp":1557745257000},"page":"2202","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Miniature Diamond-Based Fiber Optic Pressure Sensor with Dual Polymer-Ceramic Adhesives"],"prefix":"10.3390","volume":"19","author":[{"given":"Hyungdae","family":"Bae","sequence":"first","affiliation":[{"name":"The Department of Mechanical Engineering, Howard University, Washington, DC 20059, USA"}]},{"given":"Ayush","family":"Giri","sequence":"additional","affiliation":[{"name":"The Department of Mechanical Engineering, Howard University, Washington, DC 20059, USA"}]},{"given":"Oluwafikunwa","family":"Kolawole","sequence":"additional","affiliation":[{"name":"The Department of Mechanical Engineering, Howard University, Washington, DC 20059, USA"}]},{"given":"Amin","family":"Azimi","sequence":"additional","affiliation":[{"name":"The Department of Mechanical Engineering, Howard University, Washington, DC 20059, USA"}]},{"given":"Aaron","family":"Jackson","sequence":"additional","affiliation":[{"name":"Howard Nanoscale Science and Engineering Facility, Department of Electrical and Computer Science, NSF STC Center for Integrated Quantum Materials, Howard University, Washington, DC 20059, USA"}]},{"given":"Gary","family":"Harris","sequence":"additional","affiliation":[{"name":"Howard Nanoscale Science and Engineering Facility, Department of Electrical and Computer Science, NSF STC Center for Integrated Quantum Materials, Howard University, Washington, DC 20059, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"981","DOI":"10.1088\/0957-0233\/7\/7\/001","article-title":"Recent progress in fibre optic low-coherence interferometry","volume":"7","author":"Rao","year":"1996","journal-title":"Meas.
