The present work aims to propose a thin films-based device, consisting of an elastic piezoelectric flapping flag clamped at one end, in order to determine the frequency of vortex shedding downstream an obstacle for a flow field at Reynolds number Re\u223c103 in the open channel. For these values, Strouhal number obtained in such way is in accordance with the results known in literature. Moreover, the development of the voltage over time, generated by the flapping flag under the load due to flow field, shows a highly fluctuating behavior and satisfies Taylor\u2019s law, observed in several complex systems. This provided useful information about the flow field through the constitutive law of the device.<\/jats:p>","DOI":"10.3390\/s21051871","type":"journal-article","created":{"date-parts":[[2021,3,8]],"date-time":"2021-03-08T04:01:25Z","timestamp":1615176085000},"page":"1871","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Direct Scaling of Measure on Vortex Shedding through a Flapping Flag Device in the Open Channel around a Cylinder at Re\u223c103: Taylor\u2019s Law Approach"],"prefix":"10.3390","volume":"21","author":[{"given":"Samuele","family":"De Bartolo","sequence":"first","affiliation":[{"name":"Department of Engineering for Innovation, EUropean Maritime Environmental Research (EUMER), University of Salento, Via per Monteroni, 73100 Lecce, Italy"}]},{"given":"Massimo De","family":"Vittorio","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, EUropean Maritime Environmental Research (EUMER), University of Salento, Via per Monteroni, 73100 Lecce, Italy"},{"name":"Center for Biomolecular Nanotechnologies (CBN), Italian Institute of Technology (IIT), Via Barsanti 14, 73100 Lecce, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7552-9193","authenticated-orcid":false,"given":"Antonio","family":"Francone","sequence":"additional","affiliation":[{"name":"Department of Civil, Environmental, Land, Construction and Chemistry Engineering, Polytechnic of Bari, Via Edoardo Orabona 4, 70125 Bari, Italy"}]},{"given":"Francesco","family":"Guido","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Nanotechnologies (CBN), Italian Institute of Technology (IIT), Via Barsanti 14, 73100 Lecce, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1998-5888","authenticated-orcid":false,"given":"Elisa","family":"Leone","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, EUropean Maritime Environmental Research (EUMER), University of Salento, Via per Monteroni, 73100 Lecce, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7782-8071","authenticated-orcid":false,"given":"Vincenzo Mariano","family":"Mastronardi","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Nanotechnologies (CBN), Italian Institute of Technology (IIT), Via Barsanti 14, 73100 Lecce, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2289-6365","authenticated-orcid":false,"given":"Andrea","family":"Notaro","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, EUropean Maritime Environmental Research (EUMER), University of Salento, Via per Monteroni, 73100 Lecce, Italy"},{"name":"School of Advanced Studies ISUFI, University of Salento, Via per Monteroni, 73100 Lecce, Italy"}]},{"given":"Giuseppe Roberto","family":"Tomasicchio","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, EUropean Maritime Environmental Research (EUMER), University of Salento, Via per Monteroni, 73100 Lecce, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,8]]},"reference":[{"key":"ref_1","unstructured":"Cengel, Y.A., and Cimbala, J.M.
