Spark technology in PEMF devices
Sometimes we are asked what the difference is between the Curatron FLASH PEMF impulse technology and the Spark PEMF technology and on this page you can read about Spark technology.
One of the best known applications is probably the use of spark gap plugs in a car motor, where delivering a very high voltage pulse [tens of thousands of volts] is used to ignite the compressed fuel and air mixture by an electric spark inside the cylinder.
In some older hospitals this same obsolete spark technology is still used to unload huge amounts of energies into underwater electrodes focused on kidneys to disintegrate kidney stones. This is called Extracorporeal Shock Wave Lithotripsy (ESWL).
The amount of energy released for this purpose is controlled by changing the very high voltage between the 14,000 and 22,000 volt level for charging the very high voltage capacitor. See how this works in the video.
All modern hospitals are also fading out this obsolete spark technology and replace their kidney stones disintegrating machines for electromagnetic systems.
In short: a spark gap is used as a very fast switch for very high voltages in the tens of thousands of volts, where a vast amount of energy is suddenly dumped e.g. into electrodes or coils. Sometimes a spark gap is called a spark chamber.
In PEMF spark-gap devices this technology is used to discharge a very high voltage capacitor into the [almost] short circuit of the cable creating a very fast and high intensity electromagnetic pulse around this cable. When this cable is folded into a loop a coil is formed, wherein the highest PEMF pulse intensity is generated.
This technology was originally developed in Greece half a century ago and applied for health purposes, but spark gap technology has become obsolete although some companies are still marketing such PEMF devices.
A spark radiates energy throughout the electromagnetic spectrum. The low frequency pulses – the maximum repetition rate is around 3 pulses per second- contain very broad and uncontrolled frequencies inside each individual impulse.
The repetition rate of the pulses per second is limited because of the time it takes between each pulse to re-charge the internal high voltage capacitor to thousands of volts required for spark gap switches. The maximum pulse frequency usually does not exceed more than a few Hertz and at the same time the intensity goes down because of the time it takes to recharge the capacitor inside the unit to the tens of thousands of volts.
This can be compared to slowly filling a bucket with water until it is full, upon which the whole contents is emptied out in one big splash. Because it takes time for this process, similarly the pulse repetition rate of a spark PEMF device is limited.
See in the video how this works ==>
In order to discharge the capacitor [charged to tens of thousands of volts] a spark gap with titanium electrodes is used to reduce the wear of the electrodes as much as possible but even these electrodes will need to be replaced after a while exactly the same way as the plugs in a car motor need to be replaced.
Replacing the very high voltage capacitor and the spark electrodes are very costly making these PEMF devices very service dependable and suffer from downtime because of repair.
The duration of the discharge pulse is very fast (less than 1 milli second) and having a peak intensity of around 1.5 Tesla but the average PEMF energy over the treatment time is only a few milli Tesla. This is the reason why the therapeutic effect of spark PEMF is for short duration only and does not treat the underlying reason for the pain.
One of the side effects of PEMF flash and spark technology is random, uncontrollable muscle contractions. These muscle contractions happen because the inducted electrical currents inside the muscles trigger the electrical contraction function of the muscles. Because of this effect seldom the maximum intensity generated by a spark device can be applied, if at all.
PEMF spark devices are intended for use of local pain relief within a short treatment time, however it has a limited lasting effect on the cause for the pain. The pain relief usually lasts for days.
Because of the very short pulses, the amount of energy inducted into the body of the person treated with these PEMF devices does not qualify for the term energy medicine.
For long term pain relief the underlying source of the pain has to be treated. For this the Curatron true PEMF technology should be used, because this not only does treat the source of the pain but in addition transfers into the human body a substantial quantity of energy and as such does treat the actual problem resulting in long lasting pain relief.
