The ASTM standard, recognized globally as a benchmark, served as a reference for analysis, ensuring test accuracy and providing a comprehensive evaluation framework. To assess the implant\u2019s usability, numerical simulations were conducted and compared against both the ASTM standard and the experimental results obtained from temporal bone studies. This investigation uncovered the bistability of periodic responses induced by the implant, prompting an analysis of the bistability in periodic solutions and the creation of basins of attraction for various initial conditions. The discovery of new solutions underscores this study\u2019s significance in the operation and reliability of implants. Consequently, this research not only enhances the theoretical comprehension of the system, but also holds promise for practical applications in the design and optimization of middle ear implants that transfer energy to the stapes and the cochlea.<\/jats:p>","DOI":"10.3390\/ma17235730","type":"journal-article","created":{"date-parts":[[2024,11,25]],"date-time":"2024-11-25T08:38:24Z","timestamp":1732523904000},"page":"5730","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Insights into Human Middle Ear Implants: Uncovered Bistability"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4857-3185","authenticated-orcid":false,"given":"Robert","family":"Zablotni","sequence":"first","affiliation":[{"name":"Department of Applied Mechanics, Mechanical Engineering Faculty, Lublin University of Technology, Nadbystrzycka 36, 20-618 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9025-4551","authenticated-orcid":false,"given":"Grzegorz","family":"Zaj\u0105c","sequence":"additional","affiliation":[{"name":"Department of Power Engineering and Transportation, Faculty of Production Engineering, University of Life Sciences in Lublin, G\u0142eboka 28, 20-612 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2808-2007","authenticated-orcid":false,"given":"Rafal","family":"Rusinek","sequence":"additional","affiliation":[{"name":"Department of Applied Mechanics, Mechanical Engineering Faculty, Lublin University of Technology, Nadbystrzycka 36, 20-618 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,23]]},"reference":[{"key":"ref_1","unstructured":"Hachmeister, J.E.
