It is important in medical field at it sends data wirelessly and it is very accurate. The accuracy and speed of data transmission are significant in medical field as lives are dependent on the data being transferred from one place to another. This communication uses wearable device which is embedded with different sensors to measure vital parameters like heartbeat, temperature, blood pressure, ECG etc. This device has ARM7 as central processing unit and provides Intra body communication using insulating material. It is very secure system and provides data in real time as the device is always on the patient’s body. This proposed method is very robust and simple communication system using human body as transmission medium. This technology provides more security than other wireless technologies. Key Words: ARM7, Sensors, Wireless technology, Intra- Body Communication, communication system, Zigbee. 1. INTRODUCTION Health is very important aspect in everybody’s life. Thus, it is essential to take good care of health. As the technology is improving many new systems are entered in health care field. There are new health monitoring devices and system which can monitor one’s health 24 hours. This is because the treatment and diagnosis is heavily dependent on the monitoring reports. Without these reports it is impossible to give treatment to the patient. Though there are new instruments available for monitoring most of them use cables and wires attached to the patient’s body. This makes them uncomfortable and system become very messy . This is mostly unbearable if the monitoring is done for longer period and continuously. Monitoring is done using different sensors which sense parameters from the patients and send them to the device. The parameters like temperature, blood pressure, ECG, heartbeat etc. plays a very vital role in medical examination and helps in correct diagnosis and deciding the treatment plan. The current system uses sensors which are wired to the monitoring devices. It makes patient uncomfortable and unable to move freely. They also tend to make the treatment difficult as wires can mess when get tangled with each other. So there is need to make things simple and error free with wireless devices. It can provide better comfort to the patient and make them mobile. This can be achieved using different wireless technologies like ZIGBEE, BLUETOOTH etc. These technologies will help in simplifying the surgical monitoring and the critical patient data can be stored in the database for better diagnosis and it can also be used for future reference[2][3]. It is clear that one sensor cannot generate data at the rapid pace and its data is in the range of few Kbits/s. So it is necessary to interconnect different sensors for more data which can be in the range of few thousands of Kbits/s. This can be achieved using wireless technology for better transmission and security. The different technologies for certain characteristics and found out that WLAN and BLUETOOTH emits lots of power i.e. power dissipation is very high. RFID and ZIGBEE provide very low data rate for transmission and therefore cannot be deployed in medical monitoring system. Following is the table shown the difference in technologies we studied for this project [1]. Table -1: Comparison of Wireless technologies Technology Frequency Data rate Transmission power Size ZIGBEE 868MHz 20 Kbits/s 1mW PCB module WLAN 2.4/5.1 GHz 54 MLitts/s 100mW PC card Active RFID 134 KHz 128 bits/s <1mW Pill BLUETOOTH 2.4 GHz 723 Kbits/s 10mW PCB module Intra-body communication <1MHz >64 Kbits/s <1mW Band aid/pill It is clear that new technology Intra-body communication has high data rate and also emits very less power which is desirable in medical monitoring. Also it is available in very small sizes which make it very suitable in surgical and critical monitoring of patients.
