Design of Wearable Health and Hazard Monitoring Device

Abstract

People face various hazardous environments on a day-to-day basis. Sometimes, it is even visible to the eye. It has a very harsh effect on the human body on a longer run. Hence, it is very essential to measure and keep track of these hazardous pollutants. Secondly, healthcare and fitness bands are now in the trend. It is becoming an essential and necessary part to keep track of metabolic activity and health conditions in the busy schedule of life. In this work, a design of a novel wearable device is proposed, which can measure the vital signs, i.e. body temperature and heart rate as well as hazardous pollutants like particular matter (PM) concentration and carbon dioxide (CO2) level of the surrounding environment. An Android application is also developed for visualization of collected data from wearable device. The main aim of designing such a device is to study the effect of these hazardous parameters on an individual basis. To check the functioning of the proposed device, it is tested on a group of six volunteers with normal body type and the collected data is analysed. It has been observed that the variation of body vital signs with respect to hazardous parameters is not same for all volunteers. Some are found to be having heart rate very much sensitive towards a higher concentration of pollutants. For a short span, body temperature variation is found to be not very significant, but for a longer exposer time, the change may be significant.
