1. An electronic device for health index measurement, comprising:

  • a power receiving section that receives a power supply voltage, in which a digital code for performing a specific control is incorporated so that a low level voltage period of a predetermined length and higher than a minimum operating voltage of an electronic device is set before a period of incorporating the digital code, and said digital code begins with a high-level voltage after said low-level voltage period, and is expressed by a variation pattern of a combination of a high-level voltage and a low-level voltage;

    a voltage measuring section configured to measure a variation of a power supply voltage that is inputted to said power receiving section;

    a signal extracting section configured to analyze the measured variation of a power supply voltage and to extract said digital code contained in the measured variation; and

    a first control section configured to perform said specific control based on said digital code extracted by said signal extracting section.
