Spikey snap-in electrodes

Skalbe · February 2019

Hi there! I am in dire need of spikey electrodes that can be connected into the snap-in wires.

It would greatly alleviate some design issues I am having as well as make it so much more easier to change the oxidized electrodes, lowering the difficulty level of maintaining the system for the final customer.

Do they exist?

How/where do I get some?

If they do not, can they be ordered to be manufactured or something?

Thank you.

Skalbe, hi.

Are you referring to these?

Sorry for not being clear. What I`m looking for is the flat snap electrodes that come with the headband kit, but with spikes.

So these here

but the kind that I could use on the hairy areas of the head.

As far as I'm aware, I have not seen spike / comb electrodes that mate with a snap connector. Instead they use the 'side gripper' type of electrode wires, that FRI also sells.

Edit: I`m looking for a spikey electrode with the same tiny plug on the back as the flat snap-in ones. I`m looking to integrate the snap-in wire design into a headset and I know that the headband kit has the sort of snap-ins where the electrodes go into the `tiny` bow connector at the end of the wire, but that wont do for what I have in mind.

Figures.

Thank you, Mr Croft, but would it be possible to arrange some kind of an order through OpenBCI or should I write to Florida Research Instruments directly?

Do you have one of these kits?

They include both types of leads, snap and side grip.

FRI is probably your best route, since they can order individual quantities of each item you want. OpenBCI primarily has the kits.

If you are into do-it-yourself type soldering and experimenting, the few posts around this one describe an 'adapter' made from two Dritz snap parts, that convert an FRI comb into an ECG snap connection. But it is bulky and kind of ugly.

Also since I have not tried this myself, not sure how well all the parts fit together. You could contact the authors of those posts by clicking on their names then using the Message button on their profiles.

I see. That is indeed rather bulky.

I will try contacting the FRI.

Thank you!
