Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
A biosensor can be sent directly to the location and a quick and easy test can be used. Biosensor implant for glucose monitoring in subcutaneous tissue (59x45x8 mm). Electronic components are hermetically enclosed in a Ti casing, while antenna and sensor probe are moulded into the epoxy header. [80]
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

BMI vs. Body Fat. We’ll start at the very beginning: Body mass index (BMI) is a measure of someone’s weight compared to their height whereas body fat percentage is a measure of how much body ...
Global efforts to address climate change will be dealt a severe blow if U.S. President-elect Donald Trump again pulls the country out of the Paris Agreement, the EU's head of climate change policy ...
Tennessee avoided an upset and remained No. 1 in the USA TODAY Sports men's basketball poll, but the rest of the top 10 got shuffled with losses.
In EIM, impedance is separated into resistance and reactance, its real and imaginary components. From this, one can compute the muscle's phase, which represents the time-shift that a sinusoid undergoes when passing through the muscle. [13] For a given resistance (R) and reactance (X), phase (θ) can be calculated.
Biosensors based on type of biotransducers. A biotransducer is the recognition-transduction component of a biosensor system. It consists of two intimately coupled parts; a bio-recognition layer and a physicochemical transducer, which acting together converts a biochemical signal to an electronic or optical signal.
