It is found that (i) in contrast to bulk and surface acoustic waves propagating in piezoelectric semiconductors, the acoustoelectric attenuation of the modes is not symmetric in respect to its maximum, (ii) a large increase in attenuation may be accompanied by a small decrease in phase velocity and vice versa, (iii) the peculiarities are valid for \u201cpure\u201d (without beam steering) and \u201cnot pure\u201d (with beam steering) modes, as well as for modes of different orders and polarizations, and (iv) conductivity of test liquid increases electromagnetic leakage between input and output transducers, affecting results of the measurements. To decrease the leakage, the liquid should be localized between transducers, outside the zone over them. If so, the mode sensitivity may be as large as 8.6 dB\/(S\/m) for amplitude and 107\u00b0\/(S\/m) for phase. However, because of comparable cross-sensitivity towards viscosity and dielectric permittivity, modes with selective detection of liquid conductivity are not found.<\/jats:p>","DOI":"10.3390\/s22197231","type":"journal-article","created":{"date-parts":[[2022,9,26]],"date-time":"2022-09-26T03:34:17Z","timestamp":1664163257000},"page":"7231","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Multimode Design and Piezoelectric Substrate Anisotropy Use to Improve Performance of Acoustic Liquid Sensors"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8854-6080","authenticated-orcid":false,"given":"Andrey","family":"Smirnov","sequence":"first","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, 125009 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Anisimkin","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, 125009 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Voronova","sequence":"additional","affiliation":[{"name":"Acoustoelectronic and Piezokeramic ELPA Corporation, 124460 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9685-0365","authenticated-orcid":false,"given":"Elizaveta","family":"Shamsutdinova","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, 125009 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mechanics and Control of Mechanical Structures, College of Aerospace Engineering, Nanjing University of Aeronautic and Astronautic, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3679-1353","authenticated-orcid":false,"given":"Hamdi","family":"Ezzin","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mechanics and Control of Mechanical Structures, College of Aerospace Engineering, Nanjing University of Aeronautic and Astronautic, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3400-8361","authenticated-orcid":false,"given":"Zhenghua","family":"Qian","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mechanics and Control of Mechanical Structures, College of Aerospace Engineering, Nanjing University of Aeronautic and Astronautic, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingfeng","family":"Ma","sequence":"additional","affiliation":[{"name":"Piezoelectric Device Laboratory, School of Mechanical Engineering and Mechanics, Ningbo University, Ningbo 315211, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1564-7179","authenticated-orcid":false,"given":"Iren","family":"Kuznetsova","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radio Engineering and Electronics of RAS, 125009 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2213","DOI":"10.1063\/1.341685","article-title":"Interaction of surface acoustic waves with a two-dimensional electron system in LiNbO3-GaAs\/AlGaAs sandwich structure","volume":"64","author":"Wixforth","year":"1988","journal-title":"J.
