The accelerometer is intended to serve as a microphone in the fully implantable hearing application which can be surgically implanted in the middle ear bone structure. For the efficient design of the accelerometer as a fully implantable biomedical device, the design parameters such as size, weight and resonant frequency have been considered. The geometrical parameters are varied to obtain the optimum sensitivity considering the design constraints and the stability of the structure. The optimised design is simulated and verified using COMSOL MULTIPHYSICS 4.2. The stability of the device is ensured using eigenfrequency analysis. Optimised results of the device geometry are presented and discussed. The accelerometer has a sensing area of 1 mm<jats:sup>2<\/jats:sup> and attains a nominal capacitance of 5.3 pF and an optimum sensitivity of 6.89 fF.<\/jats:p>","DOI":"10.1515\/bmt-2016-0181","type":"journal-article","created":{"date-parts":[[2017,11,3]],"date-time":"2017-11-03T19:17:50Z","timestamp":1509736670000},"page":"699-708","source":"Crossref","is-referenced-by-count":5,"title":["Sensitivity enhancement of a folded beam MEMS capacitive accelerometer-based microphone for fully implantable hearing application"],"prefix":"10.1515","volume":"63","author":[{"given":"Apoorva","family":"Dwivedi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gargi","family":"Khanna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref171","doi-asserted-by":"crossref","first-page":"e110636","DOI":"10.1371\/journal.pone.0110636","article-title":"Carina\u00ae and Esteem\u00ae: a systematic review of fully implantable hearing devices","volume":"9","year":"2014","journal-title":"PLoS One"},{"key":"ref201","doi-asserted-by":"crossref","first-page":"775","DOI":"10.1097\/00129492-200309000-00015","article-title":"Rehabilitation for high-frequency sensorineural hearing impairment in adults with the Symphonix Vibrant Soundbridge: a comparative study","volume":"24","year":"2003","journal-title":"Otol Neurotol"},{"key":"ref301","doi-asserted-by":"crossref","first-page":"417","DOI":"10.1016\/S0030-6665(05)70340-6","article-title":"Total implantation of the implex TICA hearing amplifier implant for high-frequency sensorineural hearing loss: the Tubingen University experience","volume":"34","year":"2001","journal-title":"Otolaryng Clin N Am"},{"key":"ref21","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1515\/BMT.2004.016","article-title":"Restoring hearing with active hearing implants\/Wiederherstellung des Geh\u00f6rs mit aktiven H\u00f6rimplantaten","volume":"49","year":"2004","journal-title":"Biomed Tech"},{"key":"ref551","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1016\/S0378-5955(00)00177-5","article-title":"Acoustic responses of the human middle ear","volume":"150","year":"2000","journal-title":"Hearing Res"},{"key":"ref621","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1109\/RBME.2008.2008250","article-title":"Cochlear implants: system design, integration, and evaluation","volume":"1","year":"2008","journal-title":"IEEE Rev Biomed Eng"},{"key":"ref251","doi-asserted-by":"crossref","first-page":"22798","DOI":"10.3390\/s150922798","article-title":"A new trans-tympanic microphone approach for fully implantable hearing devices","volume":"15","year":"2015","journal-title":"Sensors"},{"key":"ref511","doi-asserted-by":"crossref","first-page":"403","DOI":"10.1177\/000348949009900515","article-title":"Cadaver middle ears as models for living ears: comparisons of middle ear input immittance","volume":"99","year":"1990","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"ref11","first-page":"79","article-title":"Fully implantable Otologics MET Carina\u2122 device for the treatment of sensorineural hearing loss.
