Does pure graphene have any effect on human health? "Recently, we obtained an original research conclusion from brain wave physics data and discovered a new way for 100% pure graphene electrically heated infrared radiation waves to affect human brain waves." This research result is expected to be used in major fields such as promoting rapid falling asleep and improving sleep in health care field. As a two-dimensional material, graphene has unique electronic, optical, thermal and mechanical properties.
Research shows that when a bias voltage is applied to a graphene film, most of the electron energy can be converted into infrared radiation. Infrared radiation is an invisible electromagnetic wave with a longer wavelength than visible light and can be further subdivided into three different wavelengths: near-infrared, mid-infrared, and far-infrared radiation. When current passes through graphene, mid-infrared rays and far-infrared rays (4-20 microns) are radiated into free space. The far-infrared emissivity of the multi-layer graphene film exceeds 90%, and the infrared radiation generated can penetrate 2-3 microns into human skin.
Medical research shows that Alpha waves and Theta waves in human brain waves have been proven to be related to the brain's creative activities, memory, perception and sleep. "Modulating and activating brain waves may be an effective and potential way to improve brain activity and recovery, especially brain wave activity at Alpha and Theta wave frequencies related to attention, inhibitory processes, memory, perception and sleep."
Research shows that the infrared radiation of graphene electric heating film can significantly promote the frequency and duration of Alpha waves and Theta waves in the human brain. After heating single-layer graphene, multi-layer graphene, water, copper and other materials, multi- layer of pure graphene film has the best effect, and when heated at 50°C, the frequency and duration of Alpha waves and Theta waves in human brain waves increase by 2.3 to 2.9 times and 3.0 to 4.1 times.
By systematically studying the effects of different operating temperatures and heating materials, the research team determined that the effective infrared radiation wave of the multi-layer graphene electric heating film is similar to the wavelength range of human body thermal radiation, both of which are 7-14 microns, and can produce strong effects on humans at the molecular level. Rotation and vibration effects. "This method of electrically heating graphene to promote brain waves provides a convenient, non-invasive way to regulate and stimulate human brain waves, which has potential applications in solving sleep problems and regulating emotions."
The research team is applying this method This research has been transformed into scientific research results, and graphene's sleep-promoting test is also undergoing medical testing in several hospitals. The test results showed that when the test subject closed his eyes, the frequency of Alpha waves and Theta waves increased, and their duration was significantly longer, making it easier for people to fall asleep.
