Pulsed Electro-Magnetic Fields
In principle, an electromagnetic field is created whenever current flows through a conductor. The four basic parameters that define an electromagnetic signal are:


Field strength



In order to have a lasting effect on health and at the same time not cause any harm, these four components must be precisely coordinated with each other (coherence). The composition of the individual signal parameters ultimately determines whether electromagnetic fields are more harmful (e.g. computer systems, mobile phones, Wi-Fi, Bluetooth, microwaves, overhead power lines, etc.) or beneficial to health (e.g. low-frequency, pulsed, electromagnetic fields), as they are used in our PEMF devices as well as in clinical applications, for prophylaxis and for general well-being.


A wave is a turbulence in space that transfers energy from one point to another. The simplest physical waveform is the sine wave. Mathematically, sine waves can be drawn on a coordinate system consisting of X and Y axes. The Y axis describes both positive and negative values. A sine wave varies cyclically on both sides above and below the Y-axis and is symmetrical to the X-axis. The most positive value is at the peak. This value is also called the amplitude peak and represents the greatest distance of the magnetic signal from its zero point. In bioelectric medicine, this amplitude peak or wave intensity is measured in Tesla (formerly Gauss).

A magnetic wave that has alternating poles (e.g. both positive and negative peaks or cycles) is called a bipolar wave. Magnetic waveforms can be manipulated by changing the electrical impulses that create the wave. This is usually done by computer control. By combining electrical voltage changes, so-called pulse packages can be created to produce a desired biological effect. The most important parameters are the rise and fall times of the wave(s). According to Liboff, the therapeutic effect of an electromagnetic wave is highly dependent on the characteristic of how quickly the rise and fall times of a wave occur. The signal characteristic is probably the most important component of the 4 parameters of an electromagnetic signal. An abrupt fall time represents a very high peak current value, which is responsible for the ionic shift in the body. The greater the ionic shift, the more intense the biological effect. In contrast to a sine wave or a static magnet, the waveforms used in the PEMF devices iMRS prime and Omnium1 systems generate a significantly higher electromotive force at the cell membrane, within the cells and in the body tissues. The “sawtooth” and “square” pulses used have rise and fall times that are much more abrupt than a conventional sine wave.

Sawtooth wave

The health benefits of the sawtooth pulse were first researched and published by Dr Bassett in 1974. Dr Bassett proved that changes in an electromagnetic signal induce an electrical voltage in the treated tissue most strongly when the signal changes abruptly, i.e. when the signal falls extremely quickly from its highest to its lowest value (fall time). This ‘piezoelectric voltage’, induced in the bone tissue by a sawtooth wave in the study, was shown to accelerate bone healing. As a result of Bassett’s work, this waveform was approved by the FDA in the US in 1979 for the treatment of non-union fractures and as an adjunct to spinal fusion (spondylodesis).

The iMRS prime and Omnium1 systems each include a whole body applicator that generates a triple sawtooth pulse. This waveform is a combination of many harmonic, non-sinusoidal signals in the low frequency range (between 0.5 and 15 Hz), known as the “biological window”. Unlike simple sine waves or static magnets, the sawtooth pulse is constantly changing, creating a continuous electromagnetic induction within the tissue. This promotes ion displacement while preventing cell fatigue. The cell remains receptive (resonant) and the effects of the electromagnetic stimulation continue long after the period of immediate application. Research shows that the sawtooth waveform provides the most lasting results in magnetic therapy. The ratio of fast rise and fall times produces maximum efficiency for effective cell stimulation.

Magnetic field intensity

Field intensity (also known as amplitude or flux density) is a quantitative description of an electromagnetic field as a function of voltage flux and direction. The unit of electromagnetic intensity is the Tesla (named after Nikola Tesla, a Serbian-born American scientist who became world-famous in the late 19th and early 20th centuries for his many inventions in the fields of electricity and magnetism). “Gauss” is an older unit of magnetic flux density that is still used as a valid unit in various countries (1 Gauss = 100 microTesla).

The components responsible for the flux density (amplitude) of a magnetic field are the wire length and diameter of the coils, the number of turns and the current (amperes) applied to the coil. Together with the induction constant and the specific resistance of the material, the flux density (magnetic field strength) can be calculated.

Diagnostic systems such as magnetic resonance tomographs generate field strengths in the Tesla range (approximately 1.5-3 Tesla), while low-frequency pulsed magnetic field systems for medical-therapeutic applications (e.g. iMRS prime and Omnium1 systems) are in the two- to three-digit microTesla range. Clinical studies show that very low flux densities are sufficient to induce positive and long-lasting biological resonance phenomena at the cell membrane. This is based on the principle of the “biological window” – a scientific study design developed and conducted by Dr Ross Adey. Adey discovered that when body cells are exposed to an electromagnetic field within a specific frequency range, they respond with enormous resonance effects, actively contributing to cell regeneration and improved oxygen transport. This principle can also be applied to flux density. Here, too, there is a narrow biological resonance window that triggers numerous beneficial effects. Scientific work by Goodman and Blank also demonstrates these biological windows in relation to field strength. They found that human cells willingly release the cell-protecting gene “heat shock protein 70” when exposed to an electromagnetic field strength of 7 to 8 microTesla. This effect is no longer observed at higher field strengths above 70-100 microTesla. From an electromagnetic point of view, the “mind” of the human cell reacts more like a soft and pleasant “whisper”.

The state-of-the-art PEMF devices iMRS prime and Omnium1 systems are equipped with this “mother tongue” and use very low flux densities within a precisely defined frequency spectrum to communicate most effectively with our body cells within this much quoted “biological window”. The result is the best possible health-promoting effect on every single cell membrane in the body.


Just as cells and cell assemblies can be stimulated to undergo certain processes and changes by chemical means (food supplements or drugs), this principle also works “energetically” with electromagnetic waves. In fact, certain processes are even better and more effective when energized. This approach perfectly describes the general mode of action of the PEMF devices iMRS prime and Omnium1 PEMF systems. They deliver precisely defined frequency beams to almost all the body’s 75 trillion cells, simultaneously and at the speed of light. The therapeutic frequency range of electromagnetic waves is now well understood. They are also known as “biological windows”. As long as frequencies are used that fall within this range, a multitude of positive cellular effects are triggered, including, in simple terms, better absorption of nutrients, the orderly removal of waste products from the inside of the cell, improved blood circulation and oxygen transport, and an overall improvement in cellular function. This is exactly what happens during a PEMF application with an iMRS prime or Omnium1 system.

A good example to illustrate this is the comparison with sound or audio frequencies: Some are uncomfortable when they are too loud, and some are too soft to hear. Electromagnetic waves are similar: There are pleasant, effective frequencies and, on the other hand, very disturbing, “loud” and intense frequencies, which we colloquially call “electrosmog”.

The whole body applicator of an iMRS prime or Omnium1 system consists of 6 non-insulated solid copper coils, divided into 3 pairs with different numbers of turns to almost perfectly mimic the natural frequencies and intensities of the earth’s magnetic field. It is these frequencies and intensities that have a very harmonious relationship with holistic health and well-being. Daily use of such a whole-body applicator, when used consistently to release stress and tension, leads to an improvement in the transport of oxygen in the cell and an optimisation of the entire metabolism.

The rate at which a vibration changes is called frequency. Vibrations spread out in waves. The distance from one wave peak to the next is called a cycle. A cycle contains both a positive peak (above the zero line) and a negative peak. The unit for this cycle is 1 Hz = one Hertz (in honor of Heinrich Hertz, a 19th century German physicist who discovered electromagnetic waves for the invention of radio). A frequency of 25 Hz corresponds to 25 oscillations (cycles) per second. Sine waves are simple oscillations used to transport energy within a given medium; the more oscillations per second, the greater the energy transfer per second. Most of us are familiar with light energy and light waves, also known as photons. However, visible light is only a very small part of the entire electromagnetic spectrum.

Similarly, sound or tone waves are only a small fraction of the total sound spectrum, and the human ear is only able to detect and respond to a very small spectrum in this range. In the application of bioelectromagnetic signals, the general rule is that the higher the frequency, the more energy is carried. However, based on Ross Adey’s principle of the “biological window”, it is also true that each individual cell in the body (just like the human eye or ear) only gives a positive response (resonance or coherence effect) to a very specific, very narrow frequency spectrum.

Most manufacturers of magnetic field systems for home use focus on higher intensities (flux densities) and higher frequency ranges, according to the motto: more is better! However, we at Swissbionic Solutions have understood that applied energy medicine within a holistic approach does not work in this way, or only to a limited extent. The iMRS prime and Omnium1 systems use natural frequency ranges and weak intensities similar to the earth’s magnetic field, which are all within the scientifically proven “biological window”. Less is more. It is nature that teaches us which frequencies are healthy and which support health and well-being without causing harm (= side effects). The human body has many natural frequency patterns. These include the heartbeat, the flow of the spinal cord, the rhythm of breathing and the electromagnetic rhythms of the human brain. John Zimmermann, a former PhD student at the University of Colorado, documented that the frequency of a “hand applicator” during its work emits an electromagnetic frequency between 7 and 8 Hz. The so-called Schumann frequencies or Schumann resonances generated within the Earth’s ionosphere have a carrier frequency of exactly 7.83 Hz. The Earth’s magnetic field has been calculated in scientific publications (Piontzik) to be 11.75 – 11.79 Hz. The alpha waves in our brain are not only very similar to the natural Schumann waves, they are graphically almost identical.

Schumann resonance

In 1954, scientists Schumann and König reported the existence of natural electromagnetic pulses on our planet. Schumann resonances are natural oscillations that occur under the influence of atmospheric lightning discharges in the space between the Earth’s surface and the ionosphere. The light energy is pumped into the Earth’s atmosphere during lightning and causes it to oscillate, mainly at very low frequencies. The resulting electromagnetic waves travel around the Earth at the speed of light and are reflected from the ionosphere to the Earth’s surface and back again. These oscillations surround the Earth with an amazingly stable fundamental frequency of exactly 7.83 Hz. This frequency, as described above, is almost identical to the alpha waves of the human brain. The carrier frequency of the Earth’s magnetic field has also been scientifically calculated to be between 11.75 and 11.79 Hz (Piontzik).
The carrier frequency of Schumann resonances is exactly 7.83 Hz. In addition, there are numerous so-called harmonics, which are harmonically dependent on the carrier frequency. Lay people are familiar with these when they sing a song together and play the respective notes in several voices, harmonically coordinated and synchronized. These harmonics are also found in the background of the earth’s energy field as separate vibrations between 14 and 35 Hz. It seems that these harmonics are also an essential enrichment for our organism.

If our organism does not have access to these natural vibrations (e.g. by working in closed buildings made of steel or concrete, by driving a car or by electromagnetic exposure to high-frequency sources such as computers, mobile phones, microwaves, wireless technologies, Bluetooth, radar, satellites, etc.), we humans become much more susceptible to diseases, metabolic activity is restricted, the immune system is weakened. Recorded strong fluctuations within the Schumann resonances on Earth could be linked to heart attacks, car accidents and a general increase in mortality (Beck 1992).

Today, there are a variety of frequencies and frequency bundles being researched and used in classical medicine. The predominant approach is the targeted application of PEMF for well-defined indications (e.g. repetitive transcranial magnetic stimulation = rTMS for depression). Frequency ranges from extremely low (ELF), 3-300 Hz, to an upper limit of 50 billion Hz (50 GHz). For holistic and safe home therapy, it is advisable to opt for medical devices certified according to the new MDR standard (2017/745) that operate in the ELF (Extremely Low Frequency) range. These systems generate waveforms (sawtooth and rectangle pulses) which, due to their physical properties, not only produce a variety of nature-identical frequencies, but also the necessary fast rise and fall times of the pulses, which are responsible for the important resonance effects on as many body cells as possible.


Resonance is a principle discovered by Galileo Galilei in 1602 while studying the pendulum. It describes the tendency of a system to oscillate with maximum amplitude (force) at a particular frequency.

A well-known practical example is a child’s swing, which behaves like a pendulum. If you “push” the swing at the exact moment of its natural oscillation interval (i.e. its resonance frequency), the oscillation will increase to its maximum amplitude (strength). Only a relatively small amount of force (intensity) is needed to do this. Any attempt to increase the amplitude of the swinging motion outside the resonance frequency will result in a weakening or even a standstill of the motion. According to this, the greatest possible resonance effect is always achieved when one “resonates” exactly synchronously with the identical fundamental frequency, thereby amplifying the natural oscillation.

Cells in the human body have the ability to vibrate, or ‘potential’. This phenomenon can be easily observed – greatly magnified with a microscope – when, for example, red blood cells move through arteries “chasing” bacteria. Electromagnetic impulses trigger a multitude of resonance phenomena on and in the cell with the help of a defined frequency spectrum and thus amplify the natural oscillation (= the potential) of the cell. The human organism consists on average of about 75 trillion cells. Each cell contains about 1 million neuropeptide receptors. When electromagnetic impulse packages are applied that are within the biological window, a high number of receptors are stimulated, which leads to an immediate optimization of numerous cell functions. This functional description is the causal working principle of PEMF. The induction (= generation of potentials by magnetic fields) in the entire human body strengthens and improves general, metabolically relevant cell functions as well as inter- and intracellular communication, ultimately positively and sustainably influencing numerous bodily functions. Incidentally, according to the current state of research and science, it has been proven that frequencies outside the biological window are not capable of triggering resonance phenomena in numerous cell structures.

This is especially true for “unnatural” frequency ranges in the KHz and MHz range, such as those used by mobile phones, wireless technologies, Wi-Fi, Bluetooth and various household appliances. The latest generation of iMRS prime and Omnium1 systems use only extremely low, and therefore very gentle and safe, frequency and intensity ranges that lie within the resonance spectrum of human cells. They represent the gold standard in high-precision, computer-controlled generation of precisely defined electromagnetic waveforms to achieve maximum cell resonance.

Biological window

Dr William Ross Adey, an Australian-born professor of anatomy and physiology, coined the term “biological window” (Adey and Bawin 1976). Adey had measured the calcium release of brain cells in rabbits and demonstrated that this effect only occurred under the influence of a very low frequency electromagnetic field (16 Hz). Since this original discovery, there has been much agreement in the science of energy medicine that “biological windows” are very important in the way that vibrations work.

A biological window describes a certain spectrum of electromagnetic energy that is “recognized” by the organism and thus triggers a positive physiological response. Signals outside this range have little or no effect, sometimes even causing a negative, toxic reaction. This can be compared to audible frequencies: There are very pleasant ones (e.g. a symphony) and very disturbing and unpleasant ones (e.g. a loud explosion that can even cause permanent damage). Numerous scientific studies have shown that living cell tissue is very good at recognizing frequencies and their intensity and, in the best cases, absorbing them and using them for its own benefit.

Organ clock

The whole-body applicators of an iMRS prime or Omnium1 system work with pre-programmed frequency bundles that change according to the time of day. This technology is based on nature’s circadian rhythm, also known as the “body clock”. This has now been medically proven and research into it was awarded the 2017 Nobel Prize in Medicine (Hall, Rosbash and Young: Discovery of the molecular mechanisms that control the sleep-wake rhythm). Traditional Chinese Medicine (TCM) also believes that vital energy flows through the 12 organs and that this flow repeats every 24 hours. The Chinese organ clock shows the flow of energy called QI (pronounced chi) through the 12 organs in relation to the time of day. Each organ has the highest energy for 2 hours. The same organ has the least energy exactly 12 hours later.

3 to 5 a.m. 4 a.m. Lung
5 to 7 a.m. 6 a.m. Large intestine
7 to 9 a.m. 8 a.m. Stomach
9 to 11 a.m. 10 a.m. Spleen
11 a.m. to 1 p.m. 12 p.m Heart
1 to 3 p.m. 2 p.m. Small intestine
3 to 5 p.m. 4 p.m. Urinary bladder
5 to 7 p.m. 6 p.m. Kidney
7 to 9 p.m. 8 p.m. Pericardium
9 to 11 p.m. 10 p.m. Triple warmer
11 p.m. to 1 a.m. 12 a.m. Gall bladder
1 to 3 a.m. 2 a.m. Liver
For example, the diagram shows that the maximum energy flow to the liver occurs at 2 o’clock at night. Correspondingly, at 2 o’clock in the afternoon, the liver has the lowest energy flow. iMRS prime and Omnium1 systems generate time-of-day pulse packages that ensure a balance for all organs and body systems depending on the local time of application. The day is divided into 4 time zones:

5 a.m. - 10 a.m.


10 a.m. - 3 p.m.


3 p.m. - 8 p.m.


8 p.m. to 5 a.m.

The very complex and most efficient triple sawtooth pulse shape generated during a whole body application with the iMRS prime or Omnium1 system is able to generate and transport a very high number of individual frequencies and the all-important harmonics simultaneously in the shortest therapy time (8-24 minutes!). In addition, the computer control of the iMRS prime or Omnium1 system reverses the polarity of the electromagnetic field (from north to south and back again) every 2 minutes. This technology prevents the cells from becoming accustomed to the applied signal, ensuring that the therapy remains effective even with repeated daily applications.

Local PEMF therapy with an iMRS prime or Omnium1 system via a pillow or spot applicator is not subject to the Chinese organ clock, as the focus of local application is on the elimination of an isolated indication (e.g. wound healing, bone healing, improvement of peripheral blood circulation, pain relief). A very effective rectangular pulse is used. The intensities for local application are deliberately higher to ensure a faster healing process.
