PEMF spark gap devices

We are sometimes asked what the difference is between the Curatron PEMF technology and the Spark Gap PEMF technology and here is some explanation on the latter.

A spark radiates energy throughout the electromagnetic spectrum. The low frequency pulses – maximum repetition rate is 3 pulses per second- contain very broad and uncontrolled frequencies inside each individual pulse.


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.

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 spark PEMF 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 decades ago and applied for health purposes, but has become obsolete technology although some companies are still marketing such PEMF devices.

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 hospitals the same spark technology is 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.

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 spark 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 does only have very limited effect on the cause for the pain. The pain relief usually lasts for hours to days.
Because of the very short pulses, the amount of energy inducted into the body of the person treated with spark PEMF 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 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. 

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.

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.


Also the very high voltage capacitor has a limited amount of recharging cycles [similar to a rechargeable battery having a limited life time too] and even if an excellent quality very high voltage capacitor is used the typical life time is between one half and one million cycles. If this kind of PEMF spark gap device is being used e.g. 3 days a week for 50 weeks and each day only for 2 hours, with one shot per second, the high voltage capacitor will die after 3 x 50 x 2 x 3,600 = 1,080,000 shots or in other words within one year.


Because typically these devices are used even less than in the above example the time span between repairs will be longer, but it will definitely happen within a few years. Both the replacement of the very high voltage capacitor and the spark gap electrodes are expensive and usually do not even happen at the same time making these PEMF devices very service dependable and suffer from downtime because of repair.
