Abstract:

Background: The availability of acute phase sensitive electronics has increased the interest in the use of bioelectric impedance to simulate human body compositions in the field of human nutrition, human biology, physiology, and sports medicine and clinical medicine.

Objective: The cost of the instrument which is available in the market is high though it is sensitive and accurate. The aim of the study is to develop a portable, accurate, sensitive, and cost-effective bioimpedance phase angle monitoring device.

Materials and Methods: The shift is quantified geometrically as the angular transformation of the ratio of the reactance (X ) to the resistance® or the phase angle (Ø). The instrument is developed with resistance, capacitance, an internal circuit, electrodes, wires, and a display monitor.

Results: The instrument is developed and calibrated. We got the phase angle values of male (n = 25) and female (n = 15) are 7.3 ± 0.28° (n = 15) and 6.83 ± 0.30° and the average being 7.05 ± 0.37° (n = 40). The cost for the development of the instrument was around 5000/-.

Conclusion: The cost of the instrument will be around 4000/- when developed in commercial basis. The instrument will be portable, sensitive, and cost-effective compared to the existing instrument.
