The current health care system faces many challenges in view of the aging population. Reducing health costs while maintaining universal and high quality of health care are among the toughest challenges nowadays. At the same time, with an increasingly mobile life style, people desire more flexibility in their relation to the health care system, such as the possibility to get in touch with health care professionals anywhere and anytime. Indeed today's tele-monitoring devices are smaller and more

... ser-friendly, and can monitor cardiovascular diseases, temperature, etc. Recent studies have shown that using tele-monitoring devices, together with patient communications, have a significant impact on efficiency of care and quality of life. A wide range of biomedical devices and systems being integrated on a chip have been developed rapidly. This paper is based on monitoring of patients. We have designed and developed a reliable patient monitoring system. In this system, we propose an assistive health monitoring system with Vital Sign, Location, Attitude Sensing, focusing on Disabled and Elderly People. This system allows the physician to be able to understand patient's scenario on the computer screen by wireless module. Here low cost, low power consumption and flexible network topology ZigBee wireless module is used to sense the remote patient data. The sensors used in this system allow monitoring blood pressure, pulse rate and also prevent the elder person or patient from fall during unconscious state using MEMS. Also we can monitor them by using a personal computer. With help of GPRS we can upload his status and using the GPS we can find location of the person. Using ZigBee, the measured data is transferred to the mobile device. Using this technique, the physical and psychological health data of patients is collected. Thus people who are wearing the sensors can get immediate help in case of emergencies. Wearable computing has the potential to revolutionize health care by decentralizing it, giving more control to the patient, and shifting the focus from treatment to prevention.
