웨어러블 디바이스를 활용한 METs 기반 모바일 헬스 케어 시스템

Abstract

Recently, as smartphone user is increasing, many researchers have developed mobile healthcare system. A new mobile healthcare system is developed using metabolic equivalent (MET) to provide highly reliable health analysis, through wearable devices such as shirt and backpack. The wearable devices include small and light-weight wireless bio-sensors and it is designed with a focus on comfort in the daily life of a wearer. It measures the ECG and acceleration signals and, through a Bluetooth module, transfers the data to mobile phone. The accelerometer data enables the system to determine the current activity of the user, such as walking, running, biking and hiking. And ECG data is used to assess heart rate of user. An Evaluation is conducted through an application, utilizing the ECG and accelerometer signals. Then, users are able to monitor their health status on the application. An application is designed and developed with the implementation of fuzzy logic with 'The Haskell and Fox Chart' based evaluation algorithm and MET for calorie calculation is used to enhance the analysis resolution for the analyzed health information. The application displays the status of the user by using pictures and graph. Finally, health data will be saved periodically on a server PC through internet.
