Hello.

I using a custom circuit of TIDA-01580.

How can get the better ECG data?

It needs impedance matching of electrode?

Hello,

Thanks for reaching out.

Which type of electrodes are being used in your application?

I would recommend referring to the latest datasheet of AFE4900 which has information about the impedance circuit for two-electrode and three-electrode configuration.

Thank you for reply.

I will use the dry electrode.

But, not yet decided the material.

it is possible use aluminum?

Aluminum is highly conductive, inexpensive and easy to manufacture, however the anodization may reduce or stop the current flow. I think Silver would perform better, if you can't use gold.
