See age related healthy body fat percentage ranges. Since body fat is expressed as a percentage of total body mass as lean muscle mass decreases your percentage of body fat increases proportionally. Im much more hesitant now anyone have any experience outputting around the 005v that the scale type units use. The electrodes are placed on the opposite hand and ankle of the subject. This provides the longest electrical path possible in the human body to allow for the most accurate measurement. Light gets arduino.

The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine impedance. Please subscribe like us on facebook. Water is around 15 body fat for neutrally. A 56 year old with less muscle mass than a 25 year old would have a higher percent of body fat. 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.

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. Two more electrodes are placed in close pro. Determining body composition using arduino. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine. The purpose of this circuit is to generate a constant current 198 microamps which is sent through the body via two electrodes. 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.

Sounds like snake oil to me. The basic principle behind this project is known as bioelectrical impedance analysis. 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. 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. I have done a lot with arduino before but its all fun and games till the project requires running current through your body. The arduino code for this project uses many steps to get the final goal of a real and imaginary output.

Looking to make a 2 contact bioelectrical impedance sensora body fat sensor with arduino.
