Arduino Body Fat Measurement

Since body fat is expressed as a percentage of total body mass as lean muscle mass decreases your percentage of body fat increases proportionally. Light gets arduino. The purpose of this circuit is to generate a constant current 198 microamps which is sent through the body via two electrodes. Introduction for our final project we have decided to use the microcontroller provided to make a device which would measure body fat percentage of ones body. I find it difficult to believe that it is possible to get a meaningful measure of body fat from a simple electrical measurement that otherwise doesnt hurt you. The electrodes are placed on the opposite hand and ankle of the subject.

This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine. Sounds like snake oil to me. This provides the longest electrical path possible in the human body to allow for the most accurate measurement. Im much more hesitant now anyone have any experience outputting around the 005v that the scale type units use.

A 56 year old with less muscle mass than a 25 year old would have a higher percent of body fat. Looking to make a 2 contact bioelectrical impedance sensora body fat sensor with arduino. Do your research and determine the science behind the measurement and what exactly is to be measured and we may be able to help with a circuit to accomplish the measurement endgroup olin lathrop. Two more electrodes are placed in close pro. This real and imaginary output will then be put through a series of equations to get a final impedance which can be combined with height and weight to find the body fat composition. The basic principle behind this project is known as bioelectrical impedance analysis.

I have done a lot with arduino before but its all fun and games till the project requires running current through your body. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine impedance. Water is around 15 body fat for neutrally. See age related healthy body fat percentage ranges. The basic principle behind this project is known as bioelectrical impedance analysis. Determining body composition using arduino.
