The CNT\/PDMS composites were ground into fragments, and a liquid-induced densification method was used to fabricate the strain sensors. The strain sensors showed high sensitivity with gauge factors (GFs) larger than 200 and a broad strain detection range up to 80%, much higher than those strain sensors based on unfragmentized CNT\/PDMS composites (GF\u00a0&lt;\u00a01). The enhanced sensitivity of the strain sensors is ascribed to the sliding of individual fragmentized-CNT\/PDMS-composite particles during mechanical deformation, which causes significant resistance change in the strain sensors. The strain sensors can differentiate mechanical stimuli and monitor various human body motions, such as bending of the fingers, human breathing, and blood pulsing.<\/jats:p>","DOI":"10.1088\/1361-6528\/aab888","type":"journal-article","created":{"date-parts":[[2018,3,21]],"date-time":"2018-03-21T15:45:06Z","timestamp":1521647106000},"page":"235501","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":78,"title":["Highly sensitive strain sensors based on fragmentized carbon nanotube\/polydimethylsiloxane composites"],"prefix":"10.1088","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1069-2157","authenticated-orcid":false,"given":"Yang","family":"Gao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoliang","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianping","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Likun","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuzhen","family":"Xuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2018,4,12]]},"reference":[{"key":"nanoaab888bib1","doi-asserted-by":"publisher","first-page":"480","DOI":"10.1021\/acsami.5b09386","type":"journal-article","article-title":"Photoenhanced patterning of metal nanowire networks for fabrication of ultraflexible transparent devices","volume":"8","author":"Song","year":"2016","journal-title":"ACS Appl.
