Külah, Haluk; Ulusah, Hasan; Chamanian, Salar; BATU, AYKAN; UĞUR, MEHMET BİROL; Yüksel, Muhammed Berat; Yılmaz, Ali Özgür; YİĞİT, HURŞİT; Koyuncuoglu, Aziz; TOPÇU, ÖZLEM; Soydan, Alper K. (2022-01-01)
© 2022 IEEE.This paper reports a fully implantable, MEMS-based, low-power, energy harvesting, next generation cochlear implant (CI). The implant includes multi-frequency piezoelectric transducers for sound detection and en...
Single Supply PWM Fully Implantable Cochlear Implant Interface Circuit with Active Charge Balancing
Yigit, H. Andac; Ulusan, Hasan; Koc, Mert; Yüksel, Muhammed Berat; Chamanian, Salar; Külah, Haluk (2021-01-01)
Low powered fully implantable cochlear implants (FICIs) untangle the aesthetic concerns and battery replacement problems of conventional cochlear implants. However, the reported FICIs lack proper charge balancing and requi...
Thin-Film PZT based Multi-Channel Acoustic MEMS Transducer for Cochlear Implant Applications
Yüksel, Muhammed Berat; Külah, Haluk (2021-01-01)
AuthorThis paper presents a multi-channel acoustic transducer that works within the audible frequency range (250-5500 Hz) and mimics the operation of the cochlea by filtering incoming sound. The transducer is composed of e...
A Pulse-Width Modulated Cochlear Implant Interface Electronics with 513 mu W Power Consumption
Yigit, Halil Andac; Ulusan, Hasan; Yüksel, Muhammed Berat; Chamanian, Salar; Çiftci, Berkay; Koyuncuoglu, Aziz; Muhtarolu, Ali; Külah, Haluk (2019-01-01)
The fully implantable cochlear implant (FICI) interface circuit proposed in this work senses sound harmonics from 8 different piezoelectric cantilever sensors, and generates pulse width modulated biphasic current outputs t...
