B. Core technology
The body composition analyzer InBody720 is precision clinical diagnostic tool
featuring the world-leading technology of Biospace. The advanced technology
used in the InBody720 is recognized both in Korea and abroad, as Biospace
obtained CE for exports to Europe and signed a technology royalty agreement
with Yamato of Japan. The key features of the InBody720 built on the advanced
technologies patented both in Korea and abroad.
Multi-frequency Measurement
The traditional body fat measurement
tools using the impedance uses one,
single frequency at 50kHz to determine
the impedance of the human body. On
the other hand, the precision body
composition analyzer InBody720 emits
multitude of frequencies including 1kHz,
5kHz, 50kHz, 250kHz, 500kHz, 1MHz,
using the multi-frequency technology that
is a way more advanced than the single-
frequency technology.The multi-frequency
technology separates the intracellular
water from the extracellular water,
minimizing the probability of errors
caused by individual variations in the
distribution of the body water or changes
of it over the period. The InBody720 can be reliably used on the patient suffering
from diseases and is capable of diagnosing diseases such as edema.
The frequency of 5kHz, 50kHz and 250kHz are used to measure the resistance
and reactance, components of body impedance, enabling it to measure the body
water accurately. This technology, exclusive to Biospace, overcomes the
limitations with the body composition analysis.
Tetrapolar 8-Point Tactile Electrode
The traditional way was to attach a tape
such as ECG electrode to the skin and
connect the tape to the impedance
reader. The biggest problem with this
methodology is a low level of accuracy,
because the measurements vary with the
locations of electrodes and how firmly the
electrodes are attached. The body
composition analysis InBody720 uses 8-
point tactile electrodes method that is
easy to implement and is known to
maintain consistency regardless of
variations in the test environment. The
patented technology in the InBody720
takes the accuracy of body composition
analysis.
