Thus, disparate flexible multifunctional devices, including pressure sensitive flexible\/stretchable displays, have drawn worldwide research attention. Electrodes maintaining conductivity and mechanical strength against deformations are indispensable components in all prospective applications. In this work, a flexible pressure mapping sensor array is developed based on patterned Ag-nanofibers (Ag-NFs) electrode through electrospinning and lithography. The metallic Ag layer is sputtered onto the electrospinning polyvinyl alcohol (PVA) NFs. A uniform and super conductive electrode layer with outstanding mechanical performance is thus formed after dissolving PVA. Followed by the traditional lithography method, a patterned electrode array (4 \u00d7 4 sensors) is obtained. Based on the newly developed triboelectric nanogenerator (TENG) technology, a flexible pressure-mapping sensor with excellent stability towards bending deformations is further demonstrated. Moreover, a letter \u201cZ\u201d is successfully visualized by this pressure sensor array, encouraging more human\u2013machine interactive implementations, such as multi-functional tactile screens.<\/jats:p>","DOI":"10.3390\/s21072413","type":"journal-article","created":{"date-parts":[[2021,3,31]],"date-time":"2021-03-31T21:37:03Z","timestamp":1617226623000},"page":"2413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Flexible Tactile Sensor Based on Patterned Ag-Nanofiber Electrodes through Electrospinning"],"prefix":"10.3390","volume":"21","author":[{"given":"Mengxiao","family":"Chen","sequence":"first","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhe","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qichong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"},{"name":"CINTRA CNRS\/NTU\/THALES, UMI3288, Research Techno Plaza, Nanyang Technological University, 50 Nanyang Drive, Singapore 637553, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bing","family":"He","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miao","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"},{"name":"CINTRA CNRS\/NTU\/THALES, UMI3288, Research Techno Plaza, Nanyang Technological University, 50 Nanyang Drive, Singapore 637553, Singapore"},{"name":"The Photonics Institute, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s42765-020-00057-5","article-title":"Elastic and stretchable functional fibers: A review of materials, fabrication methods, and applications","volume":"3","author":"Chen","year":"2021","journal-title":"Adv.
