The present invention relates to a preparation of an energy mineral sheet, wherein energy-containing precious stones and mineral ceramics are sintered at high temperature together with magnetic minerals, and the preparation is completed by adding other polymer carriers through nano-processing. This energy mineral sheet can be made in conjunction with heat-conducting elements. This invented energy entity has effects of naturally radiating safe far-infrared and negative-ion energy, which can be applied to human body as personal physical items for promoting blood flow velocity, balancing the body electric field, and assisting health. Depending on the use conditions, this invention can be applied to prepare products such as comfortable wearable fabrics or protective gear with suitable shapes and hardness. Also, conductive fiber yarn can be used together to make products useful for detecting the body's heart rate signals and physiological information. The obtained information is then determined by an electronic controller and reacted back to the energy material of this invention to ensure the effect of promoting energy radiation for health protection.
