Feature 1SCHUMANN WAVES: Schumann waves (nonfree radiation) are extremely low frequency and can penetrate any substance. When a person is excited by Schumann waves, frequency resonance is generated, and the strength of the resonance is related to the internal structure of the electrical network (human body). 2RESONANCE: Some people have a better electrical network structure and can easily receive Schumann waves, while others can only receive weak Schumann waves, similar to the frequency tuning of a radio. 3NATURAL ENERGY: Schumann waves are natural energy, inexhaustible, and anyone who can easily resonate with Schumann waves is equal to being constantly recharged, naturally full of energy and healthy. 4MAINTAIN BALANCE: Through the received Schumann wave electromagnetic field and the body's cellular frequency resonance, maintain the overall balance of human meridians, thus reducing the damage caused by EMF free radiation to the human body. 5SIMULATION OF GEOMAGNETIC FIELD: When simulating the natural regenerative geomagnetic field through electronic methods, the body frequency resonance can be induced to supplement the natural geomagnetic and artificially attenuated EMF interference, so that the cell membrane potential balance of health.Item Type: Schumann Wave GeneratorMaterial: PCBOutput: 7.83Hz Pulse Square WaveInterface: Mini USB .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x SchumannWaveGenerator1 x USBCable
