Abstract

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.
