Bioelectrical Impedance Analyzer (BIA)

Project Overview

The world is going into a state where most of our work can be done at home and the new Corona virus pandemic was a great example for that. This change can be considered a development to make our lives easier, but there’s a side where this change can be a disadvantages for a lot of people. People will tend to work from home for hours and that will lead to a lack of activity which in its self will increase obesity rates around the world. Statistics show that obesity rates in the world and especially Saudi Arabia are increasing year by year which is a huge problem that should be taken in consideration. Obesity contributes in many disease including high blood pressure, stroke, type 2 diabetes, heart diseases and other.

This project aims to build a bioelectrical impedance analyzer that can measure human body impedance in order to estimate body fat percentage. The goal of this project is to spread awareness to people about obesity and healthcare, to encourage people to adopt a healthy lifestyle, and to use bioelectrical techniques to illustrate body fat percentage. This project will be a significant help in the medical field and it can be used in many places such as hospitals, gyms, and even at homes. In order to find the results needed, the user will need to stand on the base of the project and connect four electrodes on both hands and legs. The machine will measure the weight, height to be entered manually on the keypad along with the age and gender. The data entered will then be calculated and shown on the LCD screen as a percentage which represents the body fat percentage.

Project Objectives

  • Increase public awareness about healthcare and obesity.
  • Encourage people to adopt a healthy lifestyle.
  • Illustrate the estimate of body fat percentage using a bioelectrical technique.
