EVOLUTION OF SMART WRIST BAND USING SENSORS

SRI KRISHNAN RAGHUNATHAN, Archana N, NIresh J

Abstract


In recent years, the integration of various electronic components and sensors with textiles to give additional functions have become more common. In this way the wrist band can be made functional while retaining the aesthetic appeal and style at lower cost which is in high demand. Smart textiles are fabrics that have been designed and manufactured to include technologies that provide the wearer with increased functionality. Smart textiles can be produced by Knitting, weaving and embroidery of conductive threads, conductive metal coating and screen printing can be used to develop wearable electronic textiles but amongst these, use of conductive inks onto textiles has gained interest due to its ease of use and manufacturing scalability.  The emergence of wireless technologies and advancements in on-body sensor design can enable change in the conventional health-care system, replacing it with wearable health- care systems, centered on the individual. Wearable monitoring systems can provide continuous physiological data, as well as better information regarding the general health of individuals. Thus, such vital-sign monitoring systems will reduce health-care costs by disease prevention and enhance the quality of life. This dissertation is aimed at developing smart band by incorporating vital-sign monitoring systems. Using this assembly the recent progress in non- invasive monitoring technologies for chronic disease management is reviewed. In particular, devices and techniques for monitoring pulse rate, and body temperatures are discussed. For our research additionally conductive ink, conductive fabrics are presented. The main aim of this project is to produce a wearable wrist band which detects vital body parameters like pulse rate, temperature using sensors, conductive ink and conductive fabric. Finally the recorded temperature and pulse rate readings are send to mobile app via Wi-Fi.
