Hyperthermia is a cancer therapy using heat and drug to accelerate the death of cancer cells by exploiting its high thermosensitivity characteristics. We focused on soft-heating method where high-frequency magnetic field is applied to the FILCT (Ferromagnetic Implant with Low Curie Temperature) implanted near affected part to produce an induction heating of about 43°C. Through application of this method, we developed a wireless temperature measurement system using the change in the magnetic permeability near Curie temperature of FILCT. In this study we aim to develop a constant heating system to measure temperature data of FILCT with wireless and automatic controlling intensity of the applied magnetic field. As a result, we confirmed that by using our system we were able to heat 1.0 g of FILCT with a temperature of 30°C that is placed at 1 cm position above the drive coil, to 43°C and maintain constant temperature heating at 42.9 ±0.3°C.
