In particular, the integration of intelligent structural health monitoring and electromagnetic (EM) shielding systems with radio frequency absorbing properties into a polymer composite laminate is still a challenge. In this paper, we present an innovative system consisting of a multi-layered thin panel which integrates nanostructured coatings to combine EM disturbance suppression and low-energy impact monitoring ability. Specifically, it is composed of a stack of dielectric and conductive layers constituting the sensing and EM-absorbing laminate (SEAL). The conductive layers are made of a polyurethane paint filled with graphene nanoplatelets (GNPs) at different concentrations to tailor the effective electrical conductivity and the functionality of the material. Basically, the panel includes a piezoresistive grid, obtained by selectively spraying onto mylar a low-conductive paint with 4.5 wt.% of GNPs and an EM-absorbing lossy sheet made of the same polyurethane paint but properly modified with a higher weight fraction (8 wt.%) of graphene. The responses of the grid\u2019s strain sensors were analyzed through quasi-static mechanical bending tests, whereas the absorbing properties were evaluated through free-space and waveguide-based measurement techniques in the X, Ku, K, and Ka bands. The experimental results were also validated by numerical simulations.<\/jats:p>","DOI":"10.3390\/s22218470","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T04:00:51Z","timestamp":1667534451000},"page":"8470","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["New Sensing and Radar Absorbing Laminate Combining Structural Damage Detection and Electromagnetic Wave Absorption Properties"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7375-9013","authenticated-orcid":false,"given":"Federico","family":"Cozzolino","sequence":"first","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2567-7646","authenticated-orcid":false,"given":"Fabrizio","family":"Marra","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6732-9893","authenticated-orcid":false,"given":"Marco","family":"Fortunato","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irene","family":"Bellagamba","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Pesce","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8985-1332","authenticated-orcid":false,"given":"Alessio","family":"Tamburrano","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8160-0803","authenticated-orcid":false,"given":"Maria Sabrina","family":"Sarto","sequence":"additional","affiliation":[{"name":"Department of Astronautical, Electrical and Energy Engineering, Sapienza University of Rome, 00184 Rome, Italy"},{"name":"Research Center for Nanotechnology Applied to Engineering, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"545","DOI":"10.2514\/2.2992","article-title":"Design and Manufacturing of Aerospace Composite Structures, State-of-the-Art Assessment","volume":"39","author":"Harris","year":"2002","journal-title":"J.
