Total body composition measurement by using bioelectric impedance analysis and its impact on obesity

We are going to propose a novel total body composition measurement device which is based on Bioelectrical-Impedance Analysis (BIA) which is temperature compensated with the aid of a computer. We are making use of aluminium electrodes for this purpose. Proximal electrodes are used to measure the voltage distant electrodes of right head and foot with an excitation current of 0.8mA at 50 KHz are used for initiation. This work signifies low power consumption and precise measurement results. 50 KHz of higher frequency is needed so that it can easily penetrate the cell membrane. Our work has adopted multi frequency serial current to measure intra and extra cellular fluid and hence to have précised accuracy. Analog blocks include Band Pass Filter (BPF), Full Wave Rectifier (FWR) etc. Digital circuits include micom and memory. Total body composition measurement includes precise measurement of Fat mass (FM), Fat Free Mass (FFM) and Total Body Water (TBW). These values are compared with skin fold thickness measurements measured by digital caliper of 200mm thickness and results are tabulated and analyzed. With the intension of producing anti obsessed society to minimize health risks this body composition analyzer is produced.
