E-Stim Systems - Micro Electrode - Bipolar Electro Butt Plug

Small in size, yet technically advanced. With a diameter of just 25 mm, the E-Stim Systems Micro Electrode is E-Stim Systems’ smallest premium insertable electrode. It was originally developed to deliver highly targeted electrical stimulation around the anal sphincter. The result is a compact bipolar electro butt plug that combines two separate contact zones, a clever V-shaped neck, and two 4 mm connectors in a total length of just 57.5 mm.
This makes the Micro a striking alternative to E-Stim’s significantly larger metal electrodes. You don’t have to start out with half a kilo of metal to get acquainted with a premium bipolar electrode. Sometimes, the most interesting technology comes in the smallest package.

E-Stim Systems’ Smallest Premium Electrode

E-Stim Systems itself calls the Micro the smallest electrode in its premium lineup. The maximum diameter is just 25 mm, roughly comparable to the thickness of an adult’s thumb.
The total length is 57.5 mm, of which approximately 23 mm is insertable. Weighing approximately 82 grams, the Micro is also significantly lighter than the larger Classic electrodes, Torpedos, and other bulky metal models. That compact size makes the Micro appealing to users who are looking for the construction and electrical properties of a premium E-Stim electrode but deliberately want to avoid using a large insertable.

Specially developed for targeted anal e-stim

The Micro was originally designed to concentrate electrical stimulation specifically around the anal sphincter. For this purpose, an electrode does not need to be particularly long. The positioning of the electrical contact zones is more important.
The short head passes through the sphincter, after which the narrow neck helps keep the electrode in place. This way, the conductive parts are located on either side of the narrower neck section.
It’s a clever example of form following function: no unnecessary length, but a compact design that aims to sit exactly where things get interesting.

V-shaped neck for stable positioning

A distinctive feature of the Micro is its special V-shaped neck. E-Stim Systems developed this shape to ensure smooth insertion and to better hold the electrode in place afterward.
The head is gently inserted until the narrower neck reaches the sphincter muscle. The transition to the neck then helps prevent unwanted slippage outward.
The wide base remains outside the body and serves as both a clear safety stop and a space for the electrical connections.

Bipolar: two contacts in one electrode

The E-Stim Micro is a bipolar electrode. This means that both electrical contact points are integrated into the same plug.
E-Stim uses a top-bottom contact design in the Classic Range. The conductive top and bottom are separated from each other, allowing the electrical signal to flow between the two contact zones.
As a result, you do not need a second separate electrode to form a complete circuit. This is an important difference from monopolar electrodes such as an ElectroRing, sound, or conductive rubber loop, which always require a second electrical contact point.

Part of the Classic Range

The Micro belongs to the original E-Stim Systems Classic Range. This series consists of Micro, Small, Medium, and Large. All models have a diameter of 25 mm; the main difference lies in their length.
The Micro is by far the shortest version and was specifically developed for shallow, targeted anal placement. The Small, Medium, and Large models retain the same slim diameter but position the electrical contact zones progressively further inward.
The name “Micro” therefore has nothing to do with the electrode being thinner than the other Classic models. All four are 25 mm thick. It is primarily the exceptionally short design that gives this model its name.

Dual 4 mm Connectors

The base features two 4 mm sockets. Each connector corresponds to one of the two electrical contact zones of the bipolar electrode.
To connect the Micro to an E-Stim Systems power box, you’ll need a suitable cable with 4 mm connectors. This cable is not included with the electrode as standard.
The Micro is also compatible with the current E-Stim 4 mm Low Profile Cable. Thanks to the angled, compact connector, less cable protrudes from the bottom of the electrode, which can be practical with this particularly low-profile plug.
E-Stim does warn, however, that due to its small size, the Micro is not compatible with the older Low Profile connectors with square edges. The current Low Profile Connection Cable is compatible.

Water-Based Lubricant for Insertion and Conductivity

E-Stim Systems recommends a water-based lubricant, including its own ElectroGel. A suitable water-based lubricant not only facilitates insertion but also ensures consistent electrical contact.
Use sufficient lubricant and never force the electrode into place. Although 25 mm is a modest size within the E-Stim range, gentle and controlled placement remains important.
The manufacturer advises against using silicone-based or hybrid lubricants with the premium electrodes. According to E-Stim Systems, condoms are also not suitable for use with these electrodes.

Dismountable for thorough cleaning

The Micro is one of the premium electrodes that can be disassembled for cleaning. Turn off the power box, disconnect the power cord, and take the electrode apart according to E-Stim Systems’ instructions.
Clean all surfaces, seams, and grooves with a mild, fragrance-free cleanser, a suitable toy cleaner, or a medical-grade cleaning solution. Avoid corrosive and strongly alkaline cleaning agents.
For additional disinfection, E-Stim Systems recommends 70% isopropyl alcohol. The manufacturer also states that the metal premium electrodes can be boiled or steam-sterilized. This may cause slight discoloration, but it does not affect performance.
Carefully dry all parts after cleaning and let them air dry completely before reassembling and storing the Micro.

Protective Storage Case

The Micro Electrode comes in a reusable protective storage case. The electrode can be safely stored inside after it has been thoroughly cleaned and dried.
This keeps the surface protected from scratches and prevents the electrode from coming into unnecessary contact with other toys during storage. For a product designed to last for years, such a simple case is surprisingly useful.

Lifetime warranty

E-Stim Systems manufactures its premium electrodes in its own workshop in the United Kingdom. The Micro is also covered by the lifetime manufacturer’s warranty.
This warranty applies to the original purchaser and is subject to E-Stim Systems’ terms and conditions. Should the electrode fail during reasonable use, the manufacturer will attempt to repair or replace it.
