Usually, this requires a distributed array of sensor pixels, whose design must be optimized according to the expected use case to reduce implementation costs while providing sufficient sensitivity. In this work, we present an unobtrusive smart floor concept based on floor tiles equipped with a printed piezoelectric sensor matrix. The sensor element adds less than 130 \u00b5m in thickness to the floor tile and offers a pressure sensitivity of 36 pC\/N for a 1 cm2 pixel size. A floor model was established to simulate how the localized pressure excitation acting on the floor spreads into the sensor layer, where the error is only 1.5%. The model is valuable for optimizing the pixel density and arrangement for event and object detection while considering the smart floor implementation in buildings. Finally, a demonstration, including wireless connection to the computer, is presented, showing the viability of the tile to detect finger touch or movement of a metallic rod.<\/jats:p>","DOI":"10.3390\/s23020603","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T03:12:15Z","timestamp":1672888335000},"page":"603","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Study of Pressure Distribution in Floor Tiles with Printed P(VDF:TrFE) Sensors for Smart Surface Applications"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5091-129X","authenticated-orcid":false,"given":"Asier","family":"Alvarez Rueda","sequence":"first","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4833-3504","authenticated-orcid":false,"given":"Philipp","family":"Sch\u00e4ffner","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8158-0112","authenticated-orcid":false,"given":"Andreas","family":"Petritz","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonas","family":"Groten","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6472-2553","authenticated-orcid":false,"given":"Andreas","family":"Tschepp","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Petersen","sequence":"additional","affiliation":[{"name":"Parador GmbH, Millenkamp 7-8, 48653 Coesfeld, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9301-1929","authenticated-orcid":false,"given":"Martin","family":"Zirkl","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"Stadlober","sequence":"additional","affiliation":[{"name":"Joanneum Research Forschungsgesellschaft mbH, Franz-Pichler-Stra\u00dfe 30, 8160 Weiz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zeid, A., Sundaram, S., Moghaddam, M., Kamarthi, S., and Marion, T.
