Provided is a portable diagnostic test apparatus including: an accommodation portion including an outer side, an inner side, and an accommodation space provided on the inner side; a hinge; and a main body coupled to the accommodation portion by the hinge, where the portable diagnostic test apparatus is configured to be opened and closed by rotating one of the accommodation portion and the main body about the hinge, and where the main body is configured to obtain a result of a measurement based on data collected from drawn blood. The main body and/or the accommodation portion includes at least one strip keeping portion configured to store at least one strip. The at least one strip keeping portion may include: a housing; a discharge portion; and a first movement portion configured to move one of the strips to the discharge portion.

Portable diagnostic test apparatus

A method of measuring skin moisture content, the method including: measuring a differential rate of a skin impedance of a predetermined skin area of a user for a predetermined period of time; and determining that the skin area is a moist area when the differential rate of skin impedance is greater than or equal to a predetermined value for a predetermined period of time, and determining that the skin area is a dry area when the differential rate of skin impedance is less than the predetermined value for the predetermined period of time.

Apparatus to measure skin moisture content and method of operating the same

An apparatus for measuring skin moisture content in a user's skin is provided. The apparatus may include a signal supplier to generate an out-of-phase signal from a voltage signal obtained from the user's skin and an in-phase signal from the voltage signal, a susceptance measurement unit to measure the susceptance of the voltage signal by synchronizing the voltage signal and the out-of-phase signal received from the signal supplier, a conductance measurement unit to measure the conductance of the voltage signal by synchronizing the voltage signal and the in-phase signal, and an output unit to output sweat gland activity information of the user based on the measured conductance and skin moisture content information of the user based on the measured susceptance.

Apparatus, method and medium measuring skin moisture content

A sensor measuring skin impedance includes a reference electrode, a current carrying electrode, and a measuring electrode for measuring impedance for current flowing between the reference electrode and the current carrying electrode. The measuring electrode is recessed with respect to the reference electrode and the current carrying electrode, allowing the measuring electrode to make contact with a user's skin after the reference electrode and current carrying electrode make contact, resulting in greater measurement accuracy.

Method and sensor measuring skin impedance

An apparatus for measuring skin moisture content, the apparatus including: an electrode unit comprising a reference (R) electrode, a current (C) electrode, and a measuring (M) electrode; an operational amplifier including an inverting input terminal that is supplied to a first voltage and connects with the R electrode, and an output terminal that connects with the C electrode; a switch controlling a connection between the output terminal and the C electrode; and a comparison control unit comparing the first voltage with a voltage at the output terminal, and controlling the switch to connect the output terminal and the C electrode when the voltage at the output terminal is less than or equal to a value that is acquired by multiplying the first voltage and a predetermined constant.
