[EEG] From the Conception to the Closing of an Earphone-type EEG Measurement Device
An earphone-type EEG device that measures brain waves only through the ear, and visualises brain waves on an app via Bluetooth connection. It was successful in measuring brain waves called alpha waves, which occur during relaxation, such as when dozing or meditating. It could be used as a BCI application for voice assistant activation by blinking, stress detection, automatic hearing threshold detection, etc.
