Sensor network for assessment of energy expenditure design based on Android

Abstract

The society changes and worldwide nutrition transition are driving the obesity epidemic. Brazil has under-gone a gradual increase in the number of overweight people, and these people needs a continuous monitoring system of energy expenditure to self control - management during several physical activities, rest and basal under free-living conditions, which medical staff requires for rehabilitation processes. The body sensor networks have numerous applications to health and wellness monitoring, for this fact, we used a sensor network composed of motion, temperature and heart rate sensor for assessment energy expenditure in free-livings conditions based on Android platform which is a new generation of smart mobile phone platform that provides different services of interconnection with sensor network. Our aim was to apply a new model of energy expenditure based of four different data and process all within a device for monitoring 24h in free-living condition and transmit prevention alarms to prevent cardiovascular accident. Such information has the potential to improve changes to a healthy life. © 2013 Springer.
