Low Power Portable EEG for Continuous Monitoring with Active Electrodes

A low power and portable EEG with active electrodes for continuous monitoring of brain waves is presented. Main innovation in the project is the development of high performance dry active electrodes, which are more practical and wearable than the conventional wet electrodes. The device was built with discrete low power analog and digital integrated circuits provided by Texas Instruments, with minimal power consumption in mind. The results obtained shows that, the device performs similar or even better than the conventional EEG systems.
