Nanomaterials Based Dry Electroencephalography Electrodes for Auditory Attention Decoding in Hearing Assistance Devices

该项目旨在与AAVAA公司建立合作关系。AAVAA公司正在开发具有通过记录和分析脑电波进行注意力检测和解码的助听器。脑电波是通过耳朵周围的皮肤和耳道内进行非侵入性记录的。该系统使用AAVAA开发的高级音频信号处理和人工智能(AI)算法来分析记录的脑波，并在不依赖任何人工干预的情况下聚焦并放大用户希望注意的声音。该系统的主要组件之一是其电极。电极是系统和皮肤之间的接口。这个项目的目标是开发干燥的软测量，可以与耳朵周围和耳道内的皮肤形成稳定和共形的接触，以便可靠地长期记录脑电波。我们的目标是解决使用干电极记录生物信号的主要挑战之一，即最大限度地减少和避免运动伪影，减少皮肤-电极界面阻抗。我们的目标是通过利用纳米材料和创新的工程设计来实现这一目标。

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.
