**5. Conclusions**

In this study, the mitigation capability of a shielded loop coil on impedance matching and transmission efficiency owing to the presence of the human body for a 6.78 MHz wireless power transfer was verified based on the suppression of the electric field. Additionally, an induced electric field and SAR reduction effect of the shielded loop coil were confirmed.
