- Design and simulation of a membranes-based acoustic sensors array for cochlear implant applications G. Quiroz H. Báez S. Mendoza M. Alemán L. Villa Física, Astronomía y Matemáticas MEMS Implant Cochlear Microphone Capacitive In this work we present the design and simulation of an ac oustic sensors array for detec ting specific frequencies in a range, and allowing their identification from a complex audio signal in order to develop an application for cochlear implants. The sensitivity is obtained when a membrane resonate s when stimulated by an audio signal which behaves as a mechanical wave. The structure of each sensor is designed with the concept of MEMS capacitive microphones, formed by a flexible membrane between two rigid backplates. The variat ion of the distance between the membrane and backplates generates a capacitance change that can pass to an electronic readout circuit. The structure has been designed as a mass- spring system where a set of springs, with the same elastic properties, holds the flexible membrane. 2014 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94231175006 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
