History

The use of electricity for entertainment purposes dates back at least as early as the 1740s. In the 1830s, insertable electrode attachments for small magnetos could be purchased. Later in the 1800s, various electric belts (some complete with "suspensory sack") were advertised as cures for impotence. In the 1920s, the

) units were also being used for electrostimulation. In the 1980s 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 1970s, 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

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.

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. The risk is mostly twofold. 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.

. Violet wands can deliver a variety of sharp, cutting, or piercing type sensations. A violet wand typically consists of a hand-held "wand" made of plastic case which encases the mechanical (Tesla coil) or solid state components; a power cable, a collet (7/16" in the United States, 11 mm in Europe), and a cone. 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.
