The requirements for fabric motion sensors suitable for children are also identified. The child subjects were instructed to wear integrated clothing with sensors of different shapes (rectangular and boat-shaped), attachment positions (at the knee and elbow joints or 4 cm below the joints). The change in voltage caused by the elongation and contraction of the fabric sensors was measured for the flexion-extension motions of the arms and legs at 60\u00b0\/s (three measurements of 10 repetitions each for the 60\u00b0 and 90\u00b0 angles, for a total of 60 repetitions). Their reliability was verified by analyzing the agreement between the fabric motion sensors and attached acceleration sensors. The experimental results showed that the fabric motion sensor that can measure children\u2019s arm and leg motions most effectively is the rectangular-shaped sensor attached 4 cm below the joint. In this study, we developed a textile piezoresistive sensor suitable for measuring the joint motion of children, and analyzed the shape and attachment position of the sensor on clothing suitable for motion sensing. We showed that it is possible to sense joint motions of the human body by using flexible fabric sensors integrated into clothing.<\/jats:p>","DOI":"10.3390\/s20010284","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T11:55:07Z","timestamp":1578052507000},"page":"284","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Evaluation of Joint Motion Sensing Efficiency According to the Implementation Method of SWCNT-Coated Fabric Motion Sensor"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0116-187X","authenticated-orcid":false,"given":"Hyun-Seung","family":"Cho","sequence":"first","affiliation":[{"name":"BK21Plus Project, Clothing &amp; Textiles, Yonsei University, Seoul 03722, Korea"}]},{"given":"Jin-Hee","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Symbiotic Life-TECH, Yonsei University, Seoul 03722, Korea"}]},{"given":"Jeong-Hwan","family":"Lee","sequence":"additional","affiliation":[{"name":"College of Science and Technology, Konkuk University, Seoul 27478, Korea"}]},{"given":"Joo-Hyeon","family":"Lee","sequence":"additional","affiliation":[{"name":"Deptartment of Clothing &amp; Textiles, Yonsei University, Seoul 03722, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141","DOI":"10.14695\/KJSOS.2017.20.3.141","article-title":"Effect of the shape and attached position of fabric sensors on the sensing performance of limb-motion sensing clothes","volume":"20","author":"Cho","year":"2017","journal-title":"Sci.
