Small single use snap type adhesive patch electrodes. These are intended for EKG and similar resting tests and may not stay on as well as standard TENS type electrodes.

There are a lot of other options for snap type adhesive patch electrodes, including clear vs. opaque, wet vs. gel adhesive, weak vs. agressive adhesive.

Some adhesive patch electrodes have a simple tab which you attach via alligator clip. There are many different kinds. At 6 cents apiece, I'm going to give them a try.

Electrodes - Breast

Conical bi-polar breast electrodes

There are all sorts of quack electronic medical gadgets coming out of China. Electronic breast enhancers are basically electronic muscle stimulators (see WebMD and MedWorld) with adjustable conical bi-polar breast electrodes. The electrodes alone are worth the price even if you already have a power source.

The Y-M1013 Breast Enhancer, by Yingzhijian Technology Manufactory, is pin compatible with standard adhesive pad electrodes.

The As-Seen-On-TV Breast Shaper, by Max Concept Technologies, which can also be purchased as part of the 3-in-1 Deluxe EMS, appears to use snap on wires like "butterfly style" adhesive pad electrodes.

If you think these look fun, check out the Laser Breast Enhancer and Enlargement machine.

Note 2: Retailers for these products don't tend to be stable but you can often find them at B2B sites like Global Sources, TradeKey, and Alibaba, with multi-thousand unit minimum purchase. If the retail links here don't work, try finding the product on a B2B or manufacturer's site, then google for the product name, model number, or other text you find there. This works well since retailers often use the exact text provided by the manufacturer.

Electrical Safety

I'm not going to offer you advice on electrical safety. There are plenty of unqualified people already trying to do that. Instead, I'll give you links to expert resources and let you make your own judgements.
