A treatment method for locally causing fever in an affected area is applied to hyperthermia therapy and bronchial asthma treatment, and a large-sized medical device or a wired fever device is often used for these treatments. Therefore, development of an implantable device capable of locally heating living tissue is expected as a minimally invasive and simple treatment method. Various wireless power feeding methods such as magnetic field resonance have been developed, but all of them require the introduction of a capacitor or the like, and thus there remains a problem in implanting them in a living body. Therefore, in this study, we focused on the principle of IH (induction heating), which is a method of heating metal in a non-contact manner, and whose heat generation is relatively easy to control. Specifically, a thin-film heating device was manufactured by inkjet printing, and the heating behavior on the surface of living tissue was evaluated.
