چکیده مقاله:
Background: Bioimpedance spectroscopy (BIS) is a device used to measure electrical impedance at
frequencies from ۰ Hz to ۱ MHz. Many clinical diagnosis and fundamental researches, especially in the
field of physiology and pathology, rely on this device. The device can be used to estimate human body
composition, through the information of total body water, extracellular fluid and intracellular fluid, fat-free
mass, and fat mass from its impedance. BIS analysis can provide physiological statuses such as ischemia,
pulmonary edema, skin cancer, and intramuscular tumors. BIS is expected to be used even more widely,
both for hospital or home-based use, particularly because BIS handy, compact, inexpensive, and less
power-consuming with adequately accurate real-time. In previous research, the BIS design was based on
the magnitude-ratio and phase-difference detection using the AD۸۳۰۲ gain-phase detector method which
resulted in an operating range between ۲۰ kHz and ۱ MHz. However, the impedance was obtained from
the logarithmic ratio magnitude which caused the device to have limited accuracy at frequencies <۲۰ kHz.
Methods: In this research, we conduct design and development of a low-cost arduino-based electrical
bioimpedance spectrometer. Results: The low-cost bioimpedance spectrometry was successfully developed
using AD۹۸۵۰ as the programmable function generator, OPA۲۱۳۴ as the OpAm of voltage-controlled current
source, AD۶۲۰A as the instrument amplifier and AD۵۳۶A as the alternating current to direct current converter
which could work accurately from ۰ Hz to ۱۰۰ kHz. Conclusion: The multi-frequency bioimpedance device
developed in this research has the capability to safely measure the impedance of the human body due to its
relatively stable electric current, which is equal to (۰.۳۷۰ ± ۰.۰۰۳) mA with frequencies ranging from ۵ to
۲۰۰ kHz and has an accuracy of over ۹۰% in the frequency range of ۱۰ Hz to ۱۰۰ kHz.
