Why Copper–Silver Electrodes Are Stronger Than Gold–Silver

Primary Reason: 

Metal Pairing Voltage

  • As you now know, copper–silver creates a ~0.46 V potential, and both metals participate actively in redox reactions.

  • Gold–silver, despite a higher theoretical EMF (0.70 V), generates much less current because gold is inert and resists electron exchange.


The Effect of Electrode Size and Surface Area

Surface area affects:

  • Contact with skin and fluids

  • Amount of ionic exchange

  • Field distribution

Smaller electrodes (like Sakamura Magrain pellets) create:

  • More focused, shallow stimulation

  • Less effective current transfer over time

  • More subtle, neuromodulatory effects

Larger electrodes (like copper ink patches) allow:

  • Greater ionic movement

  • Deeper penetration of the electric field

  • More pronounced physiological effect (especially for pain or detox)
