This study proposed an electric moxibustion apparatus equipped with a semiconductor chip and charged a built-in battery using a wireless charger, and developed a prototype to measure its efficiency. The features of the moxibustion apparatus prototype with wireless charging are as follows; First, it is made in a compact structure so that it can be easily charged by consisting of a power unit and a main unit. It was revealed that the power transfer efficiency between the two units reached 38%, and that it was generally maintained at a constant value even when the transfer efficiency decreased. Second, a semiconductor is used for the heating element and temperature sensor to heat the acupuncture points. This method has a faster response speed and can control the temperature with high precision without overshooting. As a result of the measurement, it was easy to implement the same temperature characteristics as the conventional moxibustion procedure, and it was possible to program the temperature waveform desired by practitioner.
