A Study on the Novel Headset-type Biopotential Recording System for Healthcare Applications

Abstract

This thesis developed systems that can measure EEG and ECG at hairless sites using a common headset-type device that most people are accustomed to. Furthermore, clinical studies were performed to validate the usability of the developed systems in healthcare applications.<br/> First, a wearable system that allows EEG measurements in-the-ear was developed and applied to the BCI. The steady-state visual evoked potential (SSVEP) is most frequently used in EEG-based BCI owing to the short user training time and fast information transfer rate (ITR). However, the SSVEP is vulnerable to noise because the SSVEP are very small, only several μV, and it is inconvenient because SSVEP is measured in the occipital lobe where the visual cortex exists. Therefore, the goal of this study was two-fold
