On the Development of a Wearable EEG Monitoring Device for Brain-related Disorders

This paper presents our recent work on the design, implementation, and testing of a portable electroencephalography (EEG) monitoring platform. The ultimate aim of this project is to develop a wearable measurement device that can help patients with brain-related disorders such as epilepsy by predicting the expected seizures before their occurrence. These types of devices are gaining an increasing interest in the domain of instrumentation and measurement due to their non-invasive autonomous operation, customizability, and portability. The proposed platform is composed of a high-sensitivity Analog Front-End (AFE) circuit controlled by a low-power System-on-Chip (SoC) module equipped with Bluetooth Low Energy (BLE). The initial experimental evaluation presented in this paper demonstrates the features of our proposed device which is capable of measuring 5 μV signals and can operate for several days on a rechargeable 3.7 V LiPo battery.
