Starting from this, in this work, we first introduce a positive and limited function to model the dielectric properties of the material constituting the membrane according to experimental evidence which highlights that electrostatic capacitance variation occurs when the membrane deforms. Therefore, we present and discuss algebraic conditions of existence, uniqueness, and stability, even with the fringing field formulated according to the Pelesko\u2013Driskoll theory, which is known to take these effects into account with terms characterized by reduced computational loads. These conditions, using \u201cgold standard\u201d numerical approaches, allow the optimal numerical recovery of the membrane profile to be achieved under different load conditions and also provide an important criterion for choosing the intended use of the device starting from the choice of the material constituting the membrane and vice versa. Finally, important insights are discussed regarding the pull-in voltage and electrostatic pressure.<\/jats:p>","DOI":"10.3390\/s23031688","type":"journal-article","created":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T02:35:10Z","timestamp":1675391710000},"page":"1688","update-policy":"https:\/\/summer-heart-0930.chufeiyun1688.workers.dev:443\/https\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Numerical Approaches for Recovering the Deformable Membrane Profile of Electrostatic Microdevices for Biomedical Applications"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/summer-heart-0930.chufeiyun1688.workers.dev:443\/https\/orcid.org\/0000-0003-3837-6671","authenticated-orcid":false,"given":"Mario","family":"Versaci","sequence":"first","affiliation":[{"name":"DICEAM Department, \u201cMediterranea\u201d University, 89124 Reggio Calabria, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/summer-heart-0930.chufeiyun1688.workers.dev:443\/https\/orcid.org\/0000-0003-0734-9136","authenticated-orcid":false,"given":"Francesco Carlo","family":"Morabito","sequence":"additional","affiliation":[{"name":"DICEAM Department, \u201cMediterranea\u201d University, 89124 Reggio Calabria, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zengerle, R., Richter, A., and Sandmaier, H.
