A Personalised ear-EEG Device

Abstract

This Master of Philosophy thesis explores the potential of using 3D printing technology to create a personalised ear-EEG device capable of measuring EEG signals within the human brain from the ear. The device features a tripolar electrode and can be customised to fit any ear shape, ensuring a comfortable fit for all patients. Another proposed solution is also made with low cost components.

To validate the performance of the ear-EEG device, various tests were conducted, including Auditory Steady-State Response (ASSR), alpha modulation, Passive Oddball (MMN), Active Oddball (P300), and Directional Hearing (N100). The results from these tests were analysed using different methods, demonstrating that the ear-EEG device performs comparably to traditional scalp-EEG in response to auditory stimuli. The findings also suggest that the device holds promise for applications in brain-computer interfaces (BCI) and seizure detection in the future development.

The future technologies and possible applications for the ear-EEG has been explored.
