In this work, an NF mat has been used as a transducer to convert acoustic signals into electric voltage outcomes. The detected voltage has been analyzed as a function of both frequency and amplitude of the excitation acoustic signal. Additionally, the detected AC signal can be retraced as a function of both frequency and amplitude with some wave distortion at relatively higher amplitudes and within a certain acoustic spectrum region. Meanwhile, the NFs have been characterized through piezoelectric responses, beta sheet calculations and surface morphology. This work is promising as a low-cost and innovative solution to harvest acoustic signals coming from wide resources of sound and noise.<\/jats:p>","DOI":"10.3390\/s20113111","type":"journal-article","created":{"date-parts":[[2020,6,2]],"date-time":"2020-06-02T09:19:27Z","timestamp":1591089567000},"page":"3111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Acoustic Energy Harvesting and Sensing via Electrospun PVDF Nanofiber Membrane"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2913-4825","authenticated-orcid":false,"given":"Nader","family":"Shehata","sequence":"first","affiliation":[{"name":"Department of Engineering Mathematics and Physics, Faculty of Engineering, Alexandria University, Alexandria 21544, Egypt"},{"name":"Faculty of Science, Utah State University, Logan, UT 84341, USA"},{"name":"The Bradley Department of Electrical and Computer Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4253-7829","authenticated-orcid":false,"given":"Ahmed H.","family":"Hassanin","sequence":"additional","affiliation":[{"name":"Center of Smart Nanotechnology and Photonics (CSNP), SmartCI Research Center of Excellence, Alexandria University, Alexandria 21544, Egypt"},{"name":"Department of Textile Engineering, Faculty of Engineering, Alexandria University, Alexandria 21544, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8296-4959","authenticated-orcid":false,"given":"Eman","family":"Elnabawy","sequence":"additional","affiliation":[{"name":"Center of Smart Nanotechnology and Photonics (CSNP), SmartCI Research Center of Excellence, Alexandria University, Alexandria 21544, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Remya","family":"Nair","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Physics, Faculty of Engineering, Alexandria University, Alexandria 21544, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameer A.","family":"Bhat","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Physics, Faculty of Engineering, Alexandria University, Alexandria 21544, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4153-8133","authenticated-orcid":false,"given":"Ishac","family":"Kandas","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Physics, Faculty of Engineering, Alexandria University, Alexandria 21544, Egypt"},{"name":"Center of Smart Nanotechnology and Photonics (CSNP), SmartCI Research Center of Excellence, Alexandria University, Alexandria 21544, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"332","DOI":"10.1038\/35104599","article-title":"Alternative energy technologies","volume":"414","author":"Dresselhaus","year":"2001","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1513","DOI":"10.1016\/j.rser.2010.11.037","article-title":"Role of renewable energy sources in environmental protection: A review","volume":"15","author":"Panwar","year":"2011","journal-title":"Renew.
