ECG sensor with Active electrodes

Postby gregaj314 » Thu Jul 28, 2016 10:44 pm

I want to purchase a set of dry-contact active ECG electrodes for long term use without irritation to the skin, (Plessey Semiconductor PS25255) and I'm concerned that the Bitalino sensor may saturate due to having too much voltage gain in the system. With the Plessey electrodes having a gain of 10, and the Bitalino ECG at 1100, the total gain would be 11,000. Is this a valid concern?

Hi there,

First of all we'd like to thank you for your interest in BITalino... indeed it may be a valid concern.

The BITalino ECG sensors have the gain in 2 stages (~10x + ~100x); if you want we can produce ECG sensor as per your specifications (e.g. without the first stage which would be ensured by the Plessey Semiconductor PS25255).

Perhaps you could even consider purchasing two sensors (a standard and an altered one) and you can test both configurations. Depending on the sensor placement (e.g. with the electrodes very close together) a higher gain may useful.

In order to proceed with such a custom setting, the best is to e-mail us to bitalino@plux.info

Best regards,
The BITalino Team
