EEG active electrode for ads1299. Thanks!

Other Parts Discussed in Thread: ADS1299, LMP7702, INA116

Hi all,

I was using the passive electrode to acquire the eeg signal using ads1299. but the cable swing induces too much artefact.

can any expert tell me where to buy the active electrode, or how to design one for ads1299 using proper buffer(amplifier)?

Thank you so so much! Appreciated.

Best,

Hey Qi,

I'm not the expert on active electrodes, but maybe the folks in the amp forum can speak to any solutions they are familiar with.

Hello Qi,

Unfortunately we are not active electrode experts either. I am aware of research at UC San Diego where they constructed active electrodes using the LMP7702. Here is a link to the publication:

www.isn.ucsd.edu/.../rbme10.pdf

It's likely that there are more recent studies, though. Hope this helps!

Hi Qi,

Not sure if you have found a solution yet but we do have a custom active electrode design that works great with the ADS1299 that uses the INA116. Very high performance. We have paired the circuitry with both gold pins and conductive silicone material for through-hair EEG.

Hi Devon,

Do you any papers or documentation available on this design?
Very interested in purchasing/designing active sensors to test with the ADS1299.

Kind regards,

Mark
