The application of graphite sheets in knee pads mainly utilizes their heating function. Graphite heating pads are commonly used in functional waist and knee protection. For example, graphite heating knee pads are equipped with graphite heating films. After heating, graphite will release far-infrared light waves, which are easily absorbed by the human body and have relatively discrete spectra. So on the surface, it feels warm and the local energy metabolism rate will be higher than the surrounding area, which can accelerate the blood circulation on the body surface and achieve therapeutic effects.
