Electrospun microfibers are a great material for this application due to their excellent properties, especially their flexibility and lightness. Their functionalization with graphene nanoplatelets (GNPs) makes them a fantastic alternative for the development of innovative conductive materials. In this work, electrospun membranes based on polycaprolactone (PCL) were impregnated with different GNPs concentrations in order to create an electrically conductive surface with piezoresistive behavior. All the samples were properly characterized, demonstrating the homogeneous distribution and the GNPs\u2019 adsorption onto the membrane\u2019s surfaces. Additionally, the electrical performance of the developed systems was studied, including the electrical conductivity, piezoresistive behavior, and Gauge Factor (GF). A maximum electrical conductivity value of 0.079 S\/m was obtained for the 2%GNPs-PCL sample. The developed piezoresistive sensor showed high sensitivity to external pressures and excellent durability to repetitive pressing. The best value of GF (3.20) was obtained for the membranes with 0.5% of GNPs. Hence, this work presents the development of a flexible piezoresistive sensor, based on electrospun PCL microfibers and GNPs, utilizing simple methods.<\/jats:p>","DOI":"10.3390\/app11031124","type":"journal-article","created":{"date-parts":[[2021,1,26]],"date-time":"2021-01-26T08:29:16Z","timestamp":1611649756000},"page":"1124","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Smart Fibrous Structures Produced by Electrospinning Using the Combined Effect of PCL\/Graphene Nanoplatelets"],"prefix":"10.3390","volume":"11","author":[{"given":"Paola","family":"Francavilla","sequence":"first","affiliation":[{"name":"Centre for Textile Science and Technology (2C2T), University of Minho, 4710-057 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7862-4687","authenticated-orcid":false,"given":"Diana P.","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Centre for Textile Science and Technology (2C2T), University of Minho, 4710-057 Guimar\u00e3es, Portugal"}]},{"given":"Joana C.","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Centre for Textile Science and Technology (2C2T), University of Minho, 4710-057 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3303-6563","authenticated-orcid":false,"given":"Raul","family":"Fangueiro","sequence":"additional","affiliation":[{"name":"Centre for Textile Science and Technology (2C2T), University of Minho, 4710-057 Guimar\u00e3es, Portugal"},{"name":"Department of Mechanical Engineering, University of Minho, 4710-057 Guimar\u00e3es, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"66","DOI":"10.4028\/www.scientific.net\/KEM.812.66","article-title":"Smart and Sustainable Materials for Military Applications Based on Natural Fibres and Silver Nanoparticles","volume":"812","author":"Ferreira","year":"2019","journal-title":"Key Eng.
