The impedance measuring device of the present invention is a self-operated
pressure point impedance measuring device. The device can quantitatively
measure the impedance of the pressure point in digital format. The
qualified impedance data can be on-line interface to a PC computer for
recording and further application using USB protocol. The configuration
of device includes a hand-held body or with a parallel connected unit as
a current loop; a flexible round point as a measuring point, and an
impedance sensing circuitry. This impedance measuring device of the
present invention can significantly provide convenience to the users for
measuring the impedance.
