Power−efficient ramped stimulation in a fully implantable cochlear implant Doğan, Mert; Topçu, Okan; Uluşan, Hasan; Yüksel, Muhammed Berat; Uğur, Mehmet Birol; Külah, Haluk (2025-12-01) Cochlear implants (CIs) are among the most established neuromodulation devices, providing auditory perception through electrical stimulation of the auditory nerve. While conventional stimulation strategies rely on symmetri...
Direct-Print 3D Electrodes for Large-Scale, High-Density, and Customizable Neural Interfaces Wang, Pingyu; Wu, Eric G.; Uluşan, Hasan; Zhao, Eric Tianjiao; Phillips, A. J.; Kling, Alexandra; Hays, Madeline Rose; Vasireddy, Praful Krishna; Madugula, Sasidhar; Vilkhu, Ramandeep; Hierlemann, Andreas; Hong, Guosong; Chichilnisky, E. J.; Melosh, Nicholas A. (2025-01-20) Silicon-based microelectronics can scalably record and modulate neural activity at high spatiotemporal resolution, but their planar form factor poses challenges in targeting 3D neural structures. A method for fabricating t...
A 4096 channel event-based multielectrode array with asynchronous outputs compatible with neuromorphic processors Cartiglia, Matteo; Costa, Filippo; Narayanan, Shyam; Bui, Cat-Vu H.; Uluşan, Hasan; Risi, Nicoletta; Haessig, Germain; Hierlemann, Andreas; Cardes, Fernando; Indiveri, Giacomo (2024-12-01) Bio-signal sensing is pivotal in medical bioelectronics. Traditional methods focus on high sampling rates, leading to large amounts of irrelevant data and high energy consumption. We introduce a self-clocked microelectrode...
A full-custom fully implantable cochlear implant system validated in vivo with an animal model Uluşan, Hasan; Yüksel, Muhammed Berat; TOPÇU, OKAN; Yiğit, H. Andaç; Yılmaz, Ali Özgür; Doğan, Mert; Gülhan Yasar, Nagihan; Kuyumcu, İbrahim; Batu, Aykan; Göksu, Nebil; Uğur, M. Birol; Külah, Haluk (2024-12-01) Realizations of fully implantable cochlear implants (FICIs) for providing adequate solution to esthetic concerns and frequent battery replacement have lacked of addressing system level criteria as a complete device. Here, ...

A MEMS-Based Thin Film Microelectrode Array For Monıtorıng of Traumatıc Brain Injury Atik, Ali Can; Topçu, Özlem; Yılmaz, Akın Mert; Balcı, Leman Dicle; Hanalioğlu, Şahin; Uluşan, Hasan; Aslan, Mahmut Kamil; Külah, Haluk (2024-11-13)
In-vitro and In-vivo Bioelectronic Interfaces for Characterizing Neuronal Signals Uluşan, Hasan (2024-09-04)
A Low-Cost Testbed for Neural Microelectrodes Bui, Cat-Vu Hu; Maliakal, Neethu; Uluşan, Hasan; Hierlemann, Andreas; Cardes, Fernando (2024-03-21)
CardioMEA: comprehensive data analysis platform for studying cardiac diseases and drug responses Lee, Jihyun; Duperrex, Eliane; El-Battrawy, Ibrahim; Hohn, Alyssa; Saguner, Ardan M.; Duru, Firat; Emmenegger, Vishalini; Cyganek, Lukas; Hierlemann, Andreas; Uluşan, Hasan (2024-01-01) Introduction In recent years, high-density microelectrode arrays (HD-MEAs) have emerged as a valuable tool in preclinical research for characterizing the electrophysiology of human induced pluripotent stem-cell-derived car...
A CMOS-based highly scalable flexible neural electrode interface Zhao, Eric T.; Hull, Jacob M.; Hemed, Nofar Mintz; Uluşan, Hasan; Bartram, Julian; Zhang, Anqi; Wang, Pingyu; Pham, Albert; Ronchi, Silvia; Huguenard, John R.; Hierlemann, Andreas; Melosh, Nicholas A. (2023-06-07) Perception, thoughts, and actions are encoded by the coordinated activity of large neuronal populations spread over large areas. However, existing electrophysiological devices are limited by their scalability in capturing ...
