Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/127939
Kind Code:
A1
Abstract:
In the present invention, charging output is generated for a power storage element when an electronic device is mounted. An electronic device is equipped with a rectifier circuit which receives radio waves in space or electric field energy of a quasi-electrostatic field and rectifies an AC signal to DC. The electronic device includes an antenna unit which is configured by a first antenna element which is a conductor used in contact with a human body in a state in which the human body is not grounded to a ground that is the earth, and a second antenna element which is a separate conductor from the first antenna element and which is provided so as not to contact the human body. An input line, through which a part of the AC signal outputted from the antenna unit is outputted from the first antenna element used in contact with the human body to the rectifier circuit, is connected in series with the rectifier circuit. A power storage element is provided to store the output of the rectifier circuit. A surface of the first antenna element contacting the human body is configured by an electrode comprising any one, or a combination, of gold, silver, aluminum, copper, iron, nickel, an alloy, a conductive resin, or a conductive rubber.
