These data were obtained by comparing the theoretical and experimental frequency dependencies of the complex electrical impedance of bulk acoustic wave (BAW) resonator loaded by mycelium film using the least-squares method. This procedure was performed for the BAW resonator with pointed films for the relative humidity range of 17%\u201356% at the room temperature. As a result, the changes of the density, shear elastic module, viscosity, and thickness of the films under study, due to the water vapor adsorption, were determined. It has been established that the properties of mycelium films are restored after removing from the water vapor. So, these results show the possibility of using investigated mycelium films as sensitive layers for acoustic humidity sensors.<\/jats:p>","DOI":"10.3390\/s20092711","type":"journal-article","created":{"date-parts":[[2020,5,11]],"date-time":"2020-05-11T12:26:30Z","timestamp":1589199990000},"page":"2711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Influence of Humidity on the Acoustic Properties of Mushroom Mycelium Films Used as Sensitive Layers for Acoustic Humidity Sensors"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1564-7179","authenticated-orcid":false,"given":"Iren","family":"Kuznetsova","sequence":"first","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Moscow 125009, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1859-0673","authenticated-orcid":false,"given":"Boris","family":"Zaitsev","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Saratov Branch, Saratov 410019, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Larissa","family":"Krasnopolskaya","sequence":"additional","affiliation":[{"name":"Gause Institute of New Antibiotics, Moscow 119435, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrey","family":"Teplykh","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Saratov Branch, Saratov 410019, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Semyonov","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Saratov Branch, Saratov 410019, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasia","family":"Avtonomova","sequence":"additional","affiliation":[{"name":"Centre for Strategic Planning of Federal Medico-Biological Agency of Russia, Moscow 119121, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mayya","family":"Ziangirova","sequence":"additional","affiliation":[{"name":"Gause Institute of New Antibiotics, Moscow 119435, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7793-1677","authenticated-orcid":false,"given":"Andrey","family":"Smirnov","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Moscow 125009, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Kolesov","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, Moscow 125009, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"149","DOI":"10.1007\/BF03218844","article-title":"Inkjet printing of polymeric resistance humidity sensor using UV-curable electrolyte inks","volume":"16","author":"Cho","year":"2008","journal-title":"Macromol.
