Microcontroller based wearable healthcare monitoring system

Abstract

Wearable remote healthcare monitoring systems have started to become one of the main building blocks of modern healthcare. It offers innovative and better ways to monitor chronic diseases or detect early deterioration. It acquires physiological signals using sensors and wirelessly transmits them to a remote healthcare station where they are monitored and analyzed for further diagnosis. This study presents the design and development of a healthcare system that monitors vital parameters namely heart rate, respiration rate, body temperature and orientation. The sensors used for them are pulse sensor, temperature sensor LM 35, a force sensitive resistor and MPU- 9150 motion sensor. The sensors have been tested at different locations and the best location for each sensor has been used. The data has been sent wirelessly to a nearby laptop using Bluetooth and subsequently it has been displayed on the laptop using a graphical user interface (GUI) made in NI LabVIEW software. The proposed system has been compared with calibrated instrumentsand results are encouraging.
