Safety[ edit ] Electrostimulation, in general, can cause tissue damage or even death if misused. The tempered and evacuated glass tubes are back-filled with noble gas, causing them to emit sparks and glow with various colors when the violet wand is powered. The use of electricity for entertainment purposes dates back at least as early as the s. In the s, insertable electrode attachments for small magnetos could be purchased.
Later in the s, various electric belts some complete with "suspensory sack" were advertised as cures for impotence. Such power sources[ dubious — discuss ] are still in medical use today and are known as EMS electrical muscle stimulation units. Some people soon found alternative uses for the Relax-A-Cizors by placing the contacts on sexual parts of the body. By the s, medical TENS transcutaneous electrical nerve stimulation units were also being used for electrostimulation. In the s the first devices manufactured specifically for erotic electrostimulation became available, in particular the Titillator and the Pleasure Box, later known as the PES Power Box.
In the s, experimenters noticed that bare speaker wires could deliver a jolt and began using recorded and live sound for electrostimulation.
At that time, there were no professionally made attachments for such play, so people built their own out of copper plumbing parts and other metal pieces with attention to resistors placed in series with the human parts to control the current for safety.
Although early e-stim units used only a simple, pulsed , sinusoidal wave , newer units use more complex wave forms and also allow for the use of ambient sound or prerecorded wave forms like music or specially designed computer files for specific types of stimulation.
There are now sites dedicated to the creation of MP3 files specifically for erotic journeys or symphonies, which can include such routines as rewards, punishments, very strong, and pleasantly soft portions. EMS units are designed to cause muscle contraction. Body toning and massage units[ edit ] An increasing number of "body toner" or "electromassage"-type power sources are being marketed directly to consumers.
Though lacking in options compared to the more expensive specialized units, these have proven to be an inexpensive method for entry level practice. Homemade power sources[ edit ] Some people craft "homemade" electrostimulation power sources, or adapt or modify commercial products such as a Hifi or DVD system that were never intended for electrostimulation of the human body.
These can be dangerous practices; such improvised devices not specifically designed for use on the human body can easily cause injury. First the device can supply too much power. Second the insulation of most devices is not suited for medical equipment. For example, a transient over-voltage on the mains input can damage the isolation of the transformer, resulting in the output terminals becoming live.
Erotic electrostimulation power sources[ edit ] Erotic electrostimulation power sources are specifically designed and manufactured for erotic use on the human body. The first analog devices became popular during the mids, and during the late s digital devices also became available. Both types usually allow for adjustments of frequency and power output levels, some with complex preset "programs" and computer controls. The setups usually consist of a "box" and electrodes connected by wiring.
Many of the boxes are portable and can be powered by batteries or come with built-in rechargeable batteries. Some units can be connected to remote operators via an Internet -connected computer or controlled via radio frequency key fobs. Units which can be powered by a 9 volt battery are preferable to those plugged into mains as they reduce the risk of accidental injury.
Electrodes[ edit ] An electrode is used to deliver the actual electrostimulation to the body. Example of woman with electrode on the chest. This is not recommended due to the risk of cardiac arrhythmia. Placing electrodes anywhere on the chest is risking current passing through the heart, which risks cardiac arrhythmia or arrest. The general rule for electrostimulation is 'only below the waist'.
The pads used with TENS units are also used in the sexual application of electrostimulation. There are also electrified nipple and breast electrodes available, but while there is disagreement within the e-stim community about their safety the most commonly held consensus is 'only below the waist'.
The electrodes can be made of metals such as gold , silver , aluminum , and stainless steel. There are also electrodes made out of conductive silicone. Conductive rubber is a cheap, flexible and efficient option. Violet wands[ edit ] Erotec Violet Wand, from Violet wands were originally electric and neon testers, but are now split into two types: Violet wands can deliver a variety of sharp, cutting, or piercing type sensations.
The collet is inside the cone end of the Violet Wand and is where glass and metal probes are inserted to be used with the wand. The cone is there to prevent sparks jumping from the collet directly to subject. Violet wands can be used anywhere on the body but should not be used around the eyes. Water-based lubricants are generally recommended. Typically it is recommended to avoid any lubricant that contains silicone since it is an insulator and hence reduces conductivity.
Practitioners of electrostimulation select lubricants for compatibility with the material of the electrodes, as well as for desirable conductive properties, which can maximize the strength and quality of the signal.
