OpenEEG hardware – Amplifiers


In 1929, a German doctor named Hans Berger announced his discovery that it was possible to record the electrical impulses of the brain and display them graphically on paper. He also discovered that these electrical impulses changed according to the brain’s activity, whether in sleep, under sedation, with lack of oxygen, and in certain neurologic disorders like epilepsy. Initially, his peers laughed at him, but eventually his discovery laid the groundwork to the field that today is known as clinical neurophysiology.

OpenEEG hardware – Amplifiers

The OpenEEG project is about making plans and software for do-it-yourself EEG devices available for free (as in GPL). It is aimed toward amateurs who would like to experiment with EEG. However, if you are a pro in any of the fields of electronics, neurofeedback, software development etc., you are of course welcome to join the mailing-list and share your wisdom.

I found the amplifier designs extremely good as a learning material. Medical instruments after development should undergo a approval process and have high product safety requirements. So above circuits to be used for study only, not for practical applications. When integrating, Medical professionals have to beta test it and after approval used for further tests. A simulated electrical noise signal source for experimentation is good enough for Degree Projects.
