How does graphene heat up?

In recent years, the words "graphene", "heat", "far infrared life wave" and other words frequently appear in our lives. Many people say that graphene heat can be better absorbed by the human body, do you know how graphene heat?
Simply understood, graphene heating is the process of converting electrical energy into heat.
After the graphene heating film is energized, the carbon molecules in the electric thermal film produce phonons, ions and electrons in the resistance, and the generated carbon molecular groups rub against each other and collide "Brownian motion" to generate heat. In this process, due to the high thermal conductivity (5300W/mK) and low heat capacity of graphene itself, after the graphene is electrified, only a small amount of heat needs to be generated, which can make its temperature rise and quickly transfer the heat out. Part of this heat energy is transmitted outward in the far infrared with a wavelength of 5-14 microns, and is almost consistent with the human body, producing "co-frequency resonance". Therefore, the heat generated by graphene can penetrate deep into the human body and be better absorbed!
