This project aims to form a collaboration between Queen's University with AAVAA Inc.AAVAA Inc. is developing hearing aids with capability of attention detection decoding by recording and analyzing brain waves. The brain waves are recorded non-invasively through the skin around the ear and within the ear canal. The system analyzes recorded brain waves known as electroencephalograms using Advanced Audio Signal Processing and Artificial Intelligence (AI) algorithm, developed by AAVAA, and focuses on and amplifies the sound that the user wishes to attend to without relying on any manual intervention.One of the main components of this system contributing to recording electroencephalography signals (brain waves) is its electrodes. Electrodes are interfaces between the system and skin.The goal of this project is to develop dry soft sensors that can form stable and conformal contact to the skin around the ear and within the ear canal for reliable long-term recording of brain waves. Our goal is to address one of the main challenges in the field of biosignals recording using dry electrodes which is minimizing and avoiding motion artifacts and reducing skin-electrode interface impedance.We aim to achieve this goal through utilizing novel materials such as nanomaterials and innovative engineering design.
