Zinc plated electrodes

Post by birdburdy » Fri Nov 09, 2018 4:00 pm

Are zinc plated electrodes ok to use?

No, definitely not. Anything zinc-plated or galvanized should be considered UNSAFE due to the risk of molecular migration into the skin tissue.

When a current is applied across an electrode some molecules will actually migrate into the skin due to the charge ionizing the metal used for the electrode. It's your typical battery or electro-plating action. This effect, called electromigration, risks leeching toxic molecules into the body.

Safe metals suitable for stimming are Stainless Steel, Aluminum, Copper, Gold, Silver and Tin

I'd agree. Zinc plating is certainly a no-no, we actually avoid any plating as over time it wears and flakes off, giving sharp metal flakes.

We use solid Aluminium and Stainless Steel.

Ok thanks, what about brass?

Brass Mineral Data
General Brass Information
Chemical Formula: Cu3Zn2
Composition: Molecular Weight = 321.42 gm
Zinc 40.69 % Zn
Copper 59.31 % Cu

with 40% Zinc I'd say no

I guess nickel is also out?

Generally yes, I personally happen to have a nickel allergy. All stainless steel contain some nickel - its what makes SS shiny, but the grades we use have the lowest nickel content possible and are generally considered to be hypoallergenic.

Ok thanks. Basically I'm trying to use metal rivets as electrodes (for custom electrodes like clothes pegs). I think copper is the safest option as they tend to not plate that. If you have any advice place let me know.

How about graphite based conductive paint?

Graphite (used in TENS pads and Conductive Rubber) is fine for stimming and is the only non-metal that is a good conductor of electricity. With graphite paint you need to check what else is in it because some additives may make it unsuitable. Same goes for many lubes and lotions.
