In this work, the magnetoimpedance (MI) effect of patterned soft ferromagnetic meander-shaped sensor elements has been investigated. They were fabricated starting from the cobalt-based amorphous ribbon using the lithography technique and chemical etching. Three-turn (S1: spacing s = 50 \u03bcm, width w = 300 \u03bcm, length l = 5 mm; S2: spacing s = 50 \u03bcm, width w = 400 \u03bcm, length l = 5 mm) and six-turn (S3: s = 40 \u03bcm, w = 250 \u03bcm, length l = 5 mm; S4: s = 40 \u03bcm, w = 250 \u03bcm and l = 8 mm) meanders were designed. The \u2018n\u2019 shaped meander part was denominated as \u201cone turn\u201d. The S4 meander possesses a maximum MI ratio calculated for the total impedance \u0394Z\/Z \u2248 250% with a sensitivity of about 36%\/Oe (for the frequency of about 45 MHz), and an MI ratio calculated for the real part of the total impedance \u0394R\/R \u2248 250% with the sensitivity of about 32%\/Oe (for the frequency of 50 MHz). Chemical etching and the length of the samples had a strong impact on the surface magnetic properties and the magnetoimpedance. A comparative analysis of the surface magnetic properties obtained by the magneto-optical Kerr technique and MI data shows that the designed ferromagnetic meander-shaped sensor elements can be recommended for high frequency sensor applications focused on the large drop analysis. Here we understand a single large drop as the water-based sample to analyze, placed onto the surface of the MI sensor element either by microsyringe (volue range 0.5\u2013500 \u03bcL) or automatic dispenser (volume range 0.1\u201350 mL).<\/jats:p>","DOI":"10.3390\/s19112468","type":"journal-article","created":{"date-parts":[[2019,5,30]],"date-time":"2019-05-30T11:07:44Z","timestamp":1559214464000},"page":"2468","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Magnetoimpedance Effect in the Ribbon-Based Patterned Soft Ferromagnetic Meander-Shaped Elements for Sensor Application"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0957-1016","authenticated-orcid":false,"given":"Zhen","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"},{"name":"School of Physics and Electronic Engineering, Xinyang Normal University, Xinyang 464000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9562-7807","authenticated-orcid":false,"given":"Anna A.","family":"Chlenova","sequence":"additional","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"},{"name":"Institute of Metal Physics UD RAS, 620016 Ekaterinburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9843-7072","authenticated-orcid":false,"given":"Elizaveta V.","family":"Golubeva","sequence":"additional","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanislav O.","family":"Volchkov","sequence":"additional","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengfei","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Engineering, Xinyang Normal University, Xinyang 464000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7498-3623","authenticated-orcid":false,"given":"Sergei V.","family":"Shcherbinin","sequence":"additional","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"},{"name":"Institute of Electrophysics UD RAS, 620016 Ekaterinburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3712-1637","authenticated-orcid":false,"given":"Galina V.","family":"Kurlyandskaya","sequence":"additional","affiliation":[{"name":"Department of Magnetism and Magnetic Nanomaterials, Ural Federal University, 620002 Ekaterinburg, Russia"},{"name":"University of the Basque Country UPV-EHU, 48940 Leioa, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,29]]},"reference":[{"key":"ref_1","unstructured":"Landau, L.D., and Lifshitz, E.M.
