This study explores the possibility of using a hybrid high-resolution Bragg grating sensor for achieving a fast response to dynamic, continuous motion and Bragg signal pattern monitoring measurement. The wavelength shift pattern for real-time monitoring in picometer units was derived by using femtosecond laser Bragg grating processing on an optical wave path with long-period grating. The possibility of measuring the demodulation system\u2019s Bragg signal pattern on the reflection spectrum of the femtosecond laser precision Bragg process and the long-period grating was confirmed. By demonstrating a practical method of wearing the sensor, the application of wearables was also explored. It is possible to present the applicability of sophisticated micro transformation measurement applications in picometer units.<\/jats:p>","DOI":"10.3390\/s21010022","type":"journal-article","created":{"date-parts":[[2020,12,22]],"date-time":"2020-12-22T20:39:29Z","timestamp":1608669569000},"page":"22","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Hybrid LPG-FBG Based High-Resolution Micro Bending Strain Sensor"],"prefix":"10.3390","volume":"21","author":[{"given":"Song-Bi","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Cognitive Science, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul 03722, Korea"}]},{"given":"Young-Jun","family":"Jung","sequence":"additional","affiliation":[{"name":"Advanced Photonics Research Institute (APRI), Gwangju Institute of Science and Technology (GIST), 1 Oryong-dong, Buk-gu, Gwangju 500-712, Korea"}]},{"given":"Hun-Kook","family":"Choi","sequence":"additional","affiliation":[{"name":"Advanced Photonics Research Institute (APRI), Gwangju Institute of Science and Technology (GIST), 1 Oryong-dong, Buk-gu, Gwangju 500-712, Korea"}]},{"given":"Ik-Bu","family":"Sohn","sequence":"additional","affiliation":[{"name":"Advanced Photonics Research Institute (APRI), Gwangju Institute of Science and Technology (GIST), 1 Oryong-dong, Buk-gu, Gwangju 500-712, Korea"}]},{"given":"Joo-Hyeon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Cognitive Science, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul 03722, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130","DOI":"10.3389\/fpsyt.2016.00130","article-title":"Development and clinical evaluation of an mhealth application for stress management","volume":"7","author":"Winslow","year":"2016","journal-title":"Front.
