International Journal of New Technology and Research (IJNTR) ISSN:2454-4116, Volume-2, Issue-4, April 2016 Pages 65-68 65 www.ijntr.org Abstract— This article aims to present research information regarding designing of a wearable biometric device that will keep an account of heart beats, body temperature and the calories burnt by the respective user. The display will be given on an android application on user’s cell. Bluetooth low energy (BLE) technology will be used for communication between the device and the application. The purpose behind designing of this device is to keep an account of user’s health parameters. The Bluetooth enables wireless communication between the device and the application.Biometric band is a device which tracks user’s pulses, calories and body temperature. The device is supported by a small battery, a Bluetooth tag and a memory. The data will be acquired with the help of pulse count detector, Thermistors and accelerometer. Index Terms— Android, Wearable, BLE, Calories, Pulse-count, Body-temperature. I. INTRODUCTION Human being of 21st century is very conscious about his lifestyle, fashions, good looking and last but not the least Health. Every other person is working out in gym or exercising on grounds or getting trained in fitness programs. Everyone wants fitness for his long life. Due to the technological development, we can have systems for analysis of our exercises or workouts. These systems will help us as well as doctors and trainers for maintaining tracks of our routine life. Thus , each and every person wants a system that will help them to keep an account of their very essential body parameters such as body temperature, pulse count, calories burnt or gained etc. There are more parameters, users want to analyze such as blood pressure, sugar level, water content etc. These system must be easy to handle, should be having long life, must consume less power and must be very easily readable. Hence a wearable device is needed which will measure these body parameters and keep track of some of earlier readings in its memory. The display of the system must be large enough so that elder people will not find any problem in reading. Thus, to keep an account of pulse count, body temperature and calories burnt by a user at one platform is a Madhura M.

The Biometric Wrist Band will measure all the above parameters and will display the same on an android application. The Biometric wrist band is a portable device which is easy to carry and light weight. Biometric wrist band is designed with a circuit having temperature sensor, pulse counter and accelerometer kept in same package. It is a device which helps user to have an account of his health parameters along with the readings at the regular interval of time. The display of the readings is provided on android based smart phones. A dedicated application is designed for the purpose. The display on application reduces the size of the device, weight of the device and thus increases the portability. This enables ease in reading and reduces the power requirement on device side. For the communication between the device and the application Bluetooth low energy is used. BLE enables wireless communication. This reduces hardware on device side and ultimately decreases power consumption and provides faster communication. Reduction in hardware and wireless communication because of Bluetooth makes Biometric wrist band cost effective. This feature makes biometric wrist band appropriate for a common man. II. LITERATURE SURVEY History A. Wearable devices The first ever wearable device we used was the calculator watch in 1980s. It was one of the life changing invention for humans. As the use of mobiles started increasing in late 90s, humans were demanding smaller mobiles and more functions. To satisfy this requirement, we invented android and Bluetooth technologies and in 2008 Ilya Fredman incorporated a hidden camera in her ear-rings.[1] This incidence changed the whole definition of wearable. People began to think of turning our day to day life wearable things for some functioning like camera, small computations etc. There onwards companies like twitter, apple, ZEDfone used normal digital wrist watches for sending and receiving messages and new era was begun. Now a days apple watch, Sony watch, Samsung watches are in demand for sending and receiving mails, calls, messages, giving information about weather and analyzing health parameters.[2] B. Wearable devices used for maintaining health parameters The first ever wearable device which will track health parameters was brought into the market by Fitbit in 2009.
