| Summary: | In this paper, the wireless power transmission system and the model of mouse with its main organs are established to simulate the electromagnetic field and electromagnetic thermal effect. The mouse is placed at the system, and the peak value of the induced electric field intensity and temperature rise of each organ are calculated. The results show that the peak value of the induced electric field intensity of the liver is the largest, which is 1.43 V/m. Temperature rise of the kidney is the largest, which is 2.736 × 10<sup>-6</sup>°C. And the results indicate that the shielding plate can effectively reduce the peak value of induced electric field intensity and temperature rise of the main organs. Then, a biosafety experimental platform for the wireless power transmission system is set up to analyze changes in biological tissue structure, immune factors, and sex hormone content. The results show that the level of immune factors in mice increase significantly, and the level of testosterone and progesterone decrease. The heart tissue structure does not change, but the liver, spleen, ovary, and testes are affected. And the liver shows the greatest morphological changes, which is consistent with the simulation results. This study provides a theoretical basis for the security assessment of the wireless power transmission system.
