Size Matters:

The electric field (EF) generated in Bio-Electrode Therapy (BeT) depends not only on voltage (potential difference), but also on:

 

Surface Area of the Electrodes

• Larger electrodes (e.g., copper and silver) allow more ionic exchange with the skin and tissues.

• Smaller electrodes (e.g., Magrain pellets) create a narrower field more localized, but less penetrating or systemic.

 

Current Density and Field Distribution

• The current density (μA/cm²) is concentrated in smaller areas with pellets, which may be useful for microsystem stimulation (e.g., auricular, Korean Hand Therapy).

• However, larger electrodes distribute the field more broadly across meridians or muscle groups better for systemic pain relief, pH balancing, or wider energy flow.

Contact Quality and Resistance

• Tiny pellets have less contact area, which increases local resistance and may weaken ion exchange.

• Larger, well-adhered metal patches ensure better EF penetration and longer-lasting therapeutic current.

Clinical Insight

Your current use of larger copper and silver electrodes, especially with the silicone conductive adhesive, gives you:

• A more stable EF over time

• Wider therapeutic reach

• Better alignment with Qi flow on whole meridians

Patients experience more profound, systemic healing responses with the newer method.

Final Thought

You might think of Magrain pellets as “needles of light and current,” excellent for precise activation, but limited in strength. Meanwhile, larger copper-silver pairs act more like “gentle energetic paddles” creating a continuous wave of healing energy.
