However, the buckling deformation of CNTs and the crack generation of graphene usually leads to an unsatisfactory strain sensing performance. In this work, we developed a universal strategy to prepare welded CNT\u2013graphene hybrids with tunable compositions and a tunable bonding strength between components by the in situ reduction of CNT\u2013graphene oxide (GO) hybrid by thermal annealing. The stiffness of the hybrid film could be tailored by both initial CNT\/GO dosage and annealing temperature, through which its electromechanical behaviors could also be defined. The strain sensor based on the CNT\u2013graphene hybrid could be applied to collect epidermal bio-signals by both capturing the faint skin deformation from wrist pulse and recording the large deformations from joint bending, which has great potential in health monitoring, motion sensing and human\u2013machine interfacing.<\/jats:p>","DOI":"10.3390\/polym16020238","type":"journal-article","created":{"date-parts":[[2024,1,15]],"date-time":"2024-01-15T04:54:38Z","timestamp":1705294478000},"page":"238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Welded Carbon Nanotube\u2013Graphene Hybrids with Tunable Strain Sensing Behavior for Wide-Range Bio-Signal Monitoring"],"prefix":"10.3390","volume":"16","author":[{"given":"Zixuan","family":"Hong","sequence":"first","affiliation":[{"name":"Center for Intense Laser Application Technology, College of Engineering Physics, Shenzhen Technology University, Shenzhen 518118, China"},{"name":"Chinese Laser Science (Shenzhen) Co., Ltd., Shenzhen 518106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zetao","family":"Zheng","sequence":"additional","affiliation":[{"name":"Center for Intense Laser Application Technology, College of Engineering Physics, Shenzhen Technology University, Shenzhen 518118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingyan","family":"Kong","sequence":"additional","affiliation":[{"name":"Frontiers Science Center for Flexible Electronics (FSCFE), Shaanxi Institute of Flexible Electronics (SIFE), Northwestern Polytechnical University (NPU), 127 West Youyi Road, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingyu","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Southern University of Science and Technology, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Center for Intense Laser Application Technology, College of Engineering Physics, Shenzhen Technology University, Shenzhen 518118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiwei","family":"Li","sequence":"additional","affiliation":[{"name":"Frontiers Science Center for Flexible Electronics (FSCFE), Shaanxi Institute of Flexible Electronics (SIFE), Northwestern Polytechnical University (NPU), 127 West Youyi Road, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jidong","family":"Shi","sequence":"additional","affiliation":[{"name":"Center for Intense Laser Application Technology, College of Engineering Physics, Shenzhen Technology University, Shenzhen 518118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1002\/eem2.12041","article-title":"Textile-based strain sensor for human motion detection","volume":"3","author":"Wang","year":"2020","journal-title":"Energy Environ.
