Implementation of a Prototype for Body-Coupled Communication Using Embedded Electronics : Implementation of a distributed system of sensors and actuators using BodyCom development board

Abstract: A wireless body network with sensors and actuators is a topical subject in current situation, because the healthcare services cannot meet peoples requirements for personal health-care. Such a network can be used to monitor the health status of e.g. elderly people and provide a drug delivery without external human interaction. In this project we will implement a prototype of a distributed system of sensors and actuator using the human body as a transmission line for communication purposes (Capacitive Body-coupled Communication), as a solution for the problem. Similar systems have been implemented earlier, using radio-based wireless communication which consumes more power and have critical security issues, compared to capacitive body-coupled communication. This document describes how the system is implemented with focus on robust gathering of sensor data from several sensors from a single node using capacitive body-coupled communication and an actuator control with user interaction.
