Design and Validation of Android Based Wireless Integrated Device for Ubiquitous Health Monitoring

Mobile wireless technologies have become more favourable for ubiquitous healthcare nowadays to provide healthcare services anytime anywhere. This paper presents Android based integrated wireless smart device and a mobile monitoring terminal to observe and analyze real time health parameters such as saturated percentage of oxygen (SpO2), heart rate and skin temperature. The device is designed and implemented using a microcontroller platform for primary processing of data and wireless communication is done through Bluetooth protocol. The developed system is clinically useful and user friendly due to its compact size, cost effectiveness, wearability and can be used widely in hospitals for post operative care, home healthcare, community healthcare and sports training. The experimental results illustrate that the mean absolute percentage error of prototype device is 0.75 % for SpO2, 1.58 % for heart rate and 0.66 % for skin temperature measurement. Correlation coefficient is also calculated to find the linear association between the standard and prototype device.
