IMPLANTABLE PROSTHESES FOR THE INNER EAR

Proceedings of the Canadian Engineering Education Association (CEEA), 2011
The aim of our research is to develop a proof-of-concept implantable vestibular prosthesis. Such a device would be capable of 6 DOF motion sensing based on MEMS technology, to mimic vestibular functions, and provide stimulus to the brain. In this paper, the feasibility of a vestibular prosthesis is reviewed.

Polaronic and Electrochemical Signatures in Group IVB (Ti, Zr, Hf) Oxides: Unified SKP–DFT Insights for Tunable Transport in Energy and Electronic Devices

Advanced Functional Materials, EarlyView.
Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Towards High‐Acuity Vision Restoration: Hybrid Retinal Prosthesis Composed of a High‐Density Multielectrode Array Integrated With Glutamatergic Cells

Advanced Functional Materials, EarlyView.
This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.
