In particular, LIG has demonstrated considerable potential in the field of high-precision human motion posture capture using flexible sensing materials. In this study, we investigated the surface morphology evolution and performance of LIG formed by varying the laser energy accumulation times. Further, to capture human motion posture, we evaluated the performance of highly accurate flexible wearable sensors based on LIG. The experimental results showed that the sensors prepared using LIG exhibited exceptional flexibility and mechanical performance when the laser energy accumulation was optimized three times. They exhibited remarkable attributes, such as high sensitivity (~41.4), a low detection limit (0.05%), a rapid time response (response time of ~150 ms; relaxation time of ~100 ms), and excellent response stability even after 2000 s at a strain of 1.0% or 8.0%. These findings unequivocally show that flexible wearable sensors based on LIG have significant potential for capturing human motion posture, wrist pulse rates, and eye blinking patterns. Moreover, the sensors can capture various physiological signals for pilots to provide real-time capturing.<\/jats:p>","DOI":"10.3390\/s24041349","type":"journal-article","created":{"date-parts":[[2024,2,19]],"date-time":"2024-02-19T11:23:57Z","timestamp":1708341837000},"page":"1349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Flexible Wearable Sensor Based on Laser-Induced Graphene for High-Precision Fine Motion Capture for Pilots"],"prefix":"10.3390","volume":"24","author":[{"given":"Xiaoqing","family":"Xing","sequence":"first","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2615-1045","authenticated-orcid":false,"given":"Yao","family":"Zou","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8614-7668","authenticated-orcid":false,"given":"Mian","family":"Zhong","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"},{"name":"Key Laboratory of Flight Techniques and Flight Safety, CAAC, Deyang 618307, China"}]},{"given":"Shichen","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Hongyun","family":"Fan","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Xia","family":"Lei","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Juhang","family":"Yin","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Jiaqing","family":"Shen","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Xinyi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, Southwest University of Science and Technology, Mianyang 621010, China"}]},{"given":"Man","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, Southwest University of Science and Technology, Mianyang 621010, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4354-6826","authenticated-orcid":false,"given":"Yong","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, Southwest University of Science and Technology, Mianyang 621010, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6327-0823","authenticated-orcid":false,"given":"Tao","family":"Tang","sequence":"additional","affiliation":[{"name":"College of Electronic and Information, Southwest Minzu University, Chengdu 610225, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0532-1279","authenticated-orcid":false,"given":"Yu","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Flight Technology, Civil Aviation Flight University of China, Deyang 618307, China"}]},{"given":"Chao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Electronic and Electrical Engineering, Civil Aviation Flight University of China, Deyang 618307, China"},{"name":"Key Laboratory of Flight Techniques and Flight Safety, CAAC, Deyang 618307, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"171724","DOI":"10.1016\/j.jallcom.2023.171724","article-title":"Transparent single crystal graphene flexible strain sensor with high sensitivity for wearable human motion monitoring","volume":"967","author":"Zhang","year":"2023","journal-title":"J.
