Study of Wearable Biosensor with Special Reference to Health Care Monitoring

Purvi Soni; Vjay Laxmi Kalyani

Abstract— Wearable Biosensors enables real time analysis of  biochemical  fluids  such  as  sweat,  saliva  and  tears  and
provides information about health conditions. As the name states, these sensors are worn on body, at wrist, in form of clothes, in mouth etc, thus termed as wearable and are used to  sense  various  diseases,  heart  rate,  pulse  rate,  body pressure, body  temperature etc, thus  termed as biosensor. The  biological  element  detected  by  biosensors  are antibodies,  enzymes  or  nucleic  acids.  These  biological elements interact with analyses to be tested and the response is  then  converted  to  electrical  signals.  The  real  time information  is  sent wire lessly  to  the monitors,  laptops  or smart phones. Wearable biosensors helps in early detection of health events and avoids hospitalization. These  sensors are used  to monitor a wide range of parameters as stated, for  the  health  and  fitness  of  individuals.  Wearable biosensors have found advantage over other biosensors as these are easy to use, low cost, flexible, and sensitive. These wearable biosensors have found wide application in cardiac monitoring, diabetics monitoring,  agriculture, bio-defense practices, environment, and drug delivery. In this research article,  we  discussed  some  of  the  research work  done  on wearable bio sensing technology and also some of the latest and  modern  wearable  biosensors  used  in  Health  care monitoring.
