Design of Smart Wearable Device for Effective Monitoring of Health Vital Signs

Abstract

Early detection and diagnosis of basic health conditions could lead to successful treatment and
reduced fatality rate in developing countries, as it is possible to extract human bio-signals and use
it to better understand the bodily health status and reaction to external factors. This new Vital
Smart System (VSS) design have in-built sensors which a user wears as a wrist band without
interfering with his/her daily life activities to monitor his/her major vital signs (BT, BP, HR), of
which current system have limitations to achieve. Using the Dynamic System Design Methodology
(DSDM), a more technically robust, cost-effective and portable real time device was designed.
This device will have an IoT interface (BLE) to connect to smart phones; a GSM interface
(SIM900A) relying on AT command framework to access defined medical personnel on the
network in cases of emergencies; optical health LEDs to alert the user; thus, enabling consistent
self-assessment of an individual’s health condition. This work is a quest to provide a generalized
smart three-in-one vital sign system to improve the monitoring and reporting of user’s health status
through optimizing the offline and online cross-interfaces of standalone sensors in line with the
country network and health delivery system.
