Topic: How can I make this static electricity device stronger? (Read 1 time) previous topic - next topic

I recently made a pretty simple device to constantly and rapidly charge a person up with static electricity.

The main part of the device is simply a cheap component called a "Negative Ion Generator".  Which runs off of AC, so I'm using a cheap inverter to convert the DC from a typical 9v battery, or 12v lipo, into usable current for the device.  The main wire off the Ion generator attaches to a piece of aluminum that is put against the skin, and another ground wire attaches to the bottom of the shoe.

It works pretty decent, and can allow someone to generate a pretty constant stream of 1/8 - 1/4 sparks from their fingers to any grounded metal.  But I want to see if I can make it stronger.

I tried ordering more Ion generators, and actually hooked 3 of them up in parallel, thinking this would drastically increase my output, however to my surprise, I saw absolutely no increase at all, in fact, it was possibly even a little weaker.  I know the lipo battery can supply more than enough power, and the inverter is rated for more current than all 3 of these things draw.

Can anyone explain why this didn't work the way I expected, or offer any advice how to make it stronger.  Would like to increase my spark length as long as possible.

Sparks need voltage, not amps. Put them in series.


No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

The length of a spark depends on voltage, not on current.  Putting ion generators in parallel will increase the current (number of electrons being moved) but no the voltage (force applied to push electrons).  For higher voltage you need to increase the turns ratio in the high-voltage transformer.  Either reduce the number of turns in the primary winding or increase the number of turns in the secondary winding.

Or increase the voltage into the transformer. That is run the ion generator at a higher voltage.

Increasing the voltage definitely makes sense, although I'm a little bit confused about how to do so in the example of static electricity, since doesn't it behave differently than typical current?

Its my understanding (and I could be wrong about some of this, so correct me if I'm mistaken on anything) that voltage boils down to one object having more negative electrons than the other.  In the sake of the static electricity I'm going for with this device, the body collects more negative electrons than its surroundings.   Its my understanding that the negative ion generator, to be simplified, constantly floods the body with negative electrons.  So isn't voltage constantly increasing, simply by more and more negative electrons flowing from the device onto the body, before they are discharged?  Basically making the body like a capacitor.

Thats why I was figuring 3 in parallel would work, is because they would all 3 be flooding the body with negative electrons 3 times as fast, and building voltage 3 times as fast.  But apparently not.  But then is it even possible to somehow increase this with a transformer instead?  And if so, how?
