Abstract

Information and communication technologies are transforming our social interactions, lifestyles, and workplaces. One of the most promising applications of information technology is healthcare and wellness management. Healthcare is moving from an approach based on the reactive responses to acute conditions to a proactive approach characterized by early detection, prevention, and long-term management of health conditions. The current trend places an emphasis on the monitoring of health conditions and the management of wellness as significant contributors to individual healthcare and wellbeing. This is particularly important in developed countries with a significant aging population, where information technology can significantly improve the management of chronic conditions and thereby improve quality of life. In particular, the continuous or even occasional recording of biomedical signals is critical for the advancement of diagnosis by using wireless wearable sensors. With advances in mobile communication, new opportunities have opened up for the development of healthcare systems that remotely monitor biomedical signals from patients. The availability of a new generation of mobile phones has had an important impact on the development of such healthcare systems, as they seamlessly integrate with a wide variety of networks (such as 3G, Bluetooth, wireless LAN, WCDMA and GSM), and thus enable the transmission of recorded biomedical signals to doctors or patients from a hospital, home, or office. A Smartphone presents a programmable monitoring platform for healthcare as people go about their daily lives. It is now possible to infer a range of behaviors on a phone in real-time, allowing users to receive feedback in response to everyday lifestyle choices that enables them to better manage their health.

INTRODUCTION

Embedded technology can be found inside everything from computerized fitness equipment to lifesaving medical monitoring devices. These systems used in medical care increasingly help to improve the quality of diagnostic tools available to physicians and treatment available to patients. With the help of heart beat sensor we can monitor the rates of the heart every second. To measure the low & high blood pressure we using blood pressure sensor. As well as we collect temperature variations and body moments sudden changes or motions in the patient’s body .These data’s can be transmitted through the Bluetooth, which is received by the smart phone. So these mobile communications to portable to be used everywhere.

SYSTEM OVERVIEW

This paper describes a wireless healthcare solution that uses Android mobile devices in a global network. The use of a global network in healthcare applications promises to replace the use of traditional healthcare systems based on wireless sensor networks, providing ease of measurement, extension of network, accessibility, and reliability.

LM35 Sensor Specification:
The LM35 series are precision integrated-circuit LM35 temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 sensor thus has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling.
