Abstract
Life expectancy at birth increases compared to the previous year. Aging
population has become a challenge to developing a low cost and efficiency healthcare
system since there are limited medical resources. Besides, the healthcare systems on the
market do not provide two way communication feature for doctor and patient. IoT healthcare monitoring system is proposed to overcome these problems. In this study, a
system consists of the prototyping of an embedded healthcare monitoring system which
is capable to measure ECG, blood pressure, pulse rate, body temperature is proposed on
DE1-SoC platform. The IoT-framework is included where the real-time data are stored at
IBM Bluemix cloud platform through the Node-RED. Web GUI is created using http
GET and POST to display the measurements and advice from doctor through Internet.
The accuracy of the sensors for developed system are evaluated through comparing the
measurement with the commercial medical devices. The average accuracy for each
sensors to measure the health parameter are 99.21% for temperature measurement, 99.26%
for pulse rate measurement, 99.17% for Systolic pressure and 98.72% for diastolic
pressure. An analysis is carried on the measurements to predict potential disease and
results are displayed on local web page. The time required for a sample data to
successfully stored in cloud is 1.5 millisecond using 100Mbps speed Internet. Ten
volunteers are invited to test the functionality of the system. Generally the measurements
from the system have accuracy over 90%. As a conclusion, the functionality of the
healthcare system in the study is proven and it is able to provide better healthcare service
to patients.
