A MULTI-FUNCTIONAL NEURAL AMPLIFIER FOR A COMPACT AND LOW-POWERED ACTIVE DRY ELECTRODE

摘要

Provided is a brainwave signal amplifier for a dry electrode. A signal detector according to an embodiment of the present invention includes an amplifier and a filter. A brainwave signal and an external interference signal are distinguished by the signal detector. An internal interference signal is removed. After that, a signal with better quality signal to noise ratio is transmitted to a signal processing device. Thereby, the performance of a brainwave measuring device using a dry electrode can be improved.
