The first ever biomagnetic signal was demonstrated in 1863 by Gerhard Baule and Richard McFee in a magnetocardiogram (MCG). They used magnetic induction coils to detect fields generated by the human heart. Over the past century and a half, technology has made great strides and the sensitivity of the equipment has also increased significantly. The introduction of SQUID (superconducting quantum interference device) technology in the early 1970s was the biggest breakthrough in this regard, and since then scientists have shown that ECG and MCG signals are almost parallel to each other.
What is SQUID Technology?
SQUID technology is a superconducting quantum interference device that uses a mechanism to measure extremely weak magnetic signals, such as subtle changes in the human body’s electromagnetic energy field. A SQUID works using a Josephson node.
A Josephson junction consists of two superconductors separated by an insulating layer so thin that electrons can pass through it. A SQUID consists of small loops of superconductors that use Josephson nodes to achieve superposition: each electron moves simultaneously in both directions. Since the current moves in two opposite directions, the electrons have the ability to act as qubits (which can theoretically be used to enable quantum computing).
Scientists use SQUID technology for a variety of testing purposes that require extremely sensitive measurement equipment, including engineering, medical and geological equipment.
HeartMath’s research on the heart magnetic field
As many people may already know, HeartMath Institute in the US is a pioneer in the field of neurocardiology. Since the 1980s, HeartMath scientists have been researching the magnetic fields produced by the heart, how they are involved in energetic communication. This energetic communication is also called cardio-electromagnetic communication.
Our heart is the most powerful source of electromagnetic energy in the human body, producing the greatest rhythmic electromagnetic field of all the organs of the body. The heart’s electromagnetic field is about 60 times greater in amplitude than the electrical activity generated by the brain. This field, measured in the form of an electrocardiogram (ECG), can be detected anywhere on the body. In addition, the magnetic field produced by the heart can be measured in all directions up to 1 meter from the body using SQUID-based magnetometers.
Following the findings that the timing between pulses of the heart’s magnetic field is modulated by different emotional states, HeartMath has conducted several studies showing that the magnetic signals generated by the heart have the ability to communicate with individuals around us to influence.
With each contraction, the heart produces electromagnetic waves under the influence of the pressure. These electromagnetic patterns are the carriers of emotional information and these are the vibrations with a higher frequency that are found in the EEG. We transfer these patterns that can be measured with the SQUID technology to our environment and are also processed by people in our environment.
HeartMath Institute scientists have discovered a direct relationship between the heart rhythm patterns and the spectral information encoded in the frequency spectra of the magnetic field emitted from the heart. Thus, information about a person’s emotional state is encoded in the heart’s magnetic field and communicated throughout the body and to the external environment.
These findings illustrate the importance of positive emotions for our health. They also explain the fact that we often feel when someone has negative energy around them, or when someone “fills the room”.
The human body is full of mechanisms to detect the external environment. These are primarily the known sensory organs, such as the eyes, ears, skin, nose and skin. With our senses we are able to perceive touch, temperature, light and sound waves.
The interaction between two people is a very sophisticated process involving many subtle factors. Most people think of verbal and non-verbal communication, such as spoken words, facial expressions, voices and gestures.
In addition, however, there is also an influential electromagnetic or communication system that works on a subconscious level. This energetic communication system is able to sense what other people are feeling and plays an important role in the extent to which we are able to communicate effectively with others. The smoothness or flow of any social interaction largely depends on establishing a spontaneous energetic connection.
Once this energetic connection is made, the other communication systems synchronize, with speech, movements, postures and pitch going along in the entrainment or coupling between individuals.
All this very subtle energetic communication is observable with SQUID technology, with which HeartMath Institute in the US works.
