Bioimpedance
Bioelectrical Impedance or BIA measurements are done by sending mild electrical signals through the body and measuring the resistance of the human body. While this might seem like a strange concept, BIA can gather a lot of information about the subject. Body fat for example, acts as an isolator, the higher the body fat, the great the impedance. BIA allows us to gain estimations of body fat percentage in a non-invasive manner. BIA can also be used to estimate the total body water of a subject.
Thanks to improved data analysis, BIA measurements can also be used to study different aspects of a subject. This makes for a great variety of potential applications.
