Abstract: 본발명은전파에의한인체영향이적은플러그를이용한무선전력방식을제공하는것이목적이이다. 일반적으로 50, 60 Hz의전기를사용하는기기의경우, 전력선회로와전기장비사이에플러그를이용하여전기에너지를공급할수 있도록구현하므로인해, 금속으로이루어진도선을직접연결하여구현하므로인해, 기존플러그는도선이외부로노출되어사람의손이나혹은피부에접촉하는경우전류가몸에흐르게되어감전되는문제점을피할수가없으며, 물과같은유체에플러그가노출되는경우, 누전이발생되어감전의위험이더욱커지는문제점을피할수가없다. 또한기존무선전력전송기술의경우송신소자와수신소자를공간에노출을통해전력이전송되기때문에, 주변에서발생되는전기장혹은자기장에의해인체에영향을주는문제점을피할수가없어전송전력이제한될수 밖에없는문제점을갖는다.
