1. Can enable DC low-voltage power supply, fast heating, high-temperature heating, and long service life;
2. Good flexibility, heating uniformly, and excellent emission of far-infrared microwaves;
3. Can be designed/packaged according to customer needs.
To achieve proper heating modules, Morion Nanotech can choose different types of graphene materials according to different application scenarios and heating requirements. By adjusting the material formula, manufacturing process, and circuit design, the graphene heating material with continuously adjustable resistance can be obtained. This material can generate heat efficiently under various voltages by only a small potential difference, as electrons move and collide with carbon atoms to produce heat. The wavelength of the far-infrared rays emitted (concentrated in the range of 5-20 um) can help promote blood circulation and is more comfortable compared to air conditioning or heating.
