Graphene is a revolutionary material that is created by peeling graphite layer by layer to obtain a quasi-two-dimensional material that is only one atom thick. This material, called graphene (Graphene), has a thickness of only about 0.335nm. A 1mm thick layer of graphite is equivalent to approximately 3 million layers of graphene. Graphene holds significant potential for applications in materials science, micro-nano processing, energy, biomedicine, and drug delivery, among other fields. It is considered a future revolutionary material and is often hailed as the “king of new materials” or “black gold.”
As a cutting-edge material, graphene is gradually influencing our daily lives. The Graphene Health House, which is based on the unique properties of graphene heating films, aims to safeguard our health. However, for more people to benefit from this technology, it requires time to mature. There are various opinions on how graphene heating films work, especially regarding their heating mechanism and how the body absorbs heat. Let’s address two common misconceptions.
People often associate materials like carbon fiber, resistance wires, and carbon black with quick heating, high temperatures, and substantial heat output. However, the graphene heating films used in Health Houses provide a comfortable heat sensation on the body without feeling too hot or burning. This difference occurs because the far-infrared wavelengths emitted by these materials are not well-matched to the human body’s absorption spectrum, which makes it harder for the body to absorb the heat. As a result, heat tends to accumulate on the skin’s surface, and we feel the temperature change more intensely.
In contrast, graphene heating films deliver heat that is evenly distributed from the skin’s surface to the epidermal and dermal layers, ensuring that the body absorbs heat evenly. Other heating materials often fail to conduct heat well, leading to localized heat accumulation that can result in uncomfortable heat sensation.
Testing shows that graphene heating films can quickly increase in temperature: within 3 seconds of being powered on, the temperature rises rapidly, and within 10 seconds, it can reach 100°C. Considering the need for comfort when in direct contact with the human body, Health Houses integrate smart designs to enhance the overall comfort experience. Graphene itself has excellent electrical and thermal conductivity, allowing for efficient heat transfer through the nine heating films in the Graphene Health House. This takes full advantage of graphene’s properties to quickly convert electrical energy into thermal energy, ensuring rapid heating, even temperature distribution, and a fast response time.
Many believe that the heating effect of graphene is overstated, but substantial testing reveals that it is far from an exaggeration. Not all heating materials release far-infrared radiation within the optimal frequency range of 6-14 microns, but graphene falls perfectly within this range.
Ideal infrared light sources must meet two key criteria: high energy output and easy absorption by the human body. Existing infrared sources are limited by Wien’s displacement law, which means they can’t meet both of these requirements:
Graphene, however, overcomes this barrier by emitting far-infrared radiation in the 6-14μm wavelength range, which is precisely where the human body absorbs infrared radiation most efficiently. This means that graphene’s far-infrared radiation offers high energy output that is concentrated and easily absorbed by the body, ensuring an ideal match between radiation and absorption for maximum therapeutic effect.
Graphene heating films’ rapid heating is backed by this unique ability to provide a comfortable, mild temperature experience. Its non-thermal effects make the user feel more at ease, offering a level of comfort and convenience that improves daily life.
Graphene heating film is a breakthrough in thermal technology, offering quick heating, comfortable body temperature regulation, and effective far-infrared radiation that is easily absorbed by the body. The misconceptions about slow heating and exaggerated effects are myths that can be debunked through scientific understanding and real-world testing. With its remarkable properties, graphene is poised to make a lasting impact on both health and everyday comfort.
