Document Type and Number:
Japanese Patent JP2019013100
Kind Code:
A
Abstract:
To wirelessly feed power to a wearable appliance mounted on a human body.SOLUTION: A wireless power feeding system is disclosed that comprises: a power transmitter 20 performing wireless power transmission by electromagnetic wave; a distance sensor 30 measuring distance between the power transmitter 20 and a human body H mounted with a wearable appliance 70 to which power is wirelessly fed by electromagnetic wave; and a controller 40 adjusting intensity of the electromagnetic wave to be transmitted from the power transmitter 20 to such a degree that the electromagnetic wave does not exert unnecessary physiological action on the human body H mounted with the wearable appliance 70 according to the distance between the human body H and the power transmitter 20, the wearable appliance 70 is an appliance to which the power can be fed with the intensity of electromagnetic wave equal to or less than such a degree that the electromagnetic wave does not exert unnecessary physiological action on the human body H, and the power transmitter 20 wirelessly feeds power to the wearable appliance 70 mounted on the human body H without exerting unnecessary physiological action on the human body H.SELECTED DRAWING: Figure 1
