Have you tried using a wire bonder?

Hello, Solomon! I think you can connect them with silver paste. You can dip the wire into the paste and then just put it on the electrode until it will dry.

Thanks Andrew and Fetisov for the wonderful  ideas, I'm trying it out to see which one works better for me.

Your question seems very interesting to me. I also would like suggest you to try use a capacitor. Maybe you could pick up the capacity and voltage for to weld and not to burn the metal electrode.

Hello Solomon, is the IMPC = Ionic Polymer-metal Composite ? 

Is it a temporary joint or a permanent one? Pls pay attention to the

crucial properties of the bond and decide about the NDT method

to characterize the quality of the bond.

Hello Adin, yes IPMC = Ionic Polymer Metal Composite and I'm looking at a temporary joint.

Hello, Solomon.

This is possible using the FIB technique in SEM microscope.
