A Wireless Device to Transmit Physiological Signal Acquisitions using Zigbee Technology

Physiological signal measurements of human body provide lots of information to physicians about patient's life. There are many signals that can be acquired from body such as heart rate, radiological and ultrasonic images, blood flow graph and so on. Monitoring and transmitting these signals whenever needed has vital importance for physicians to be prevented from unwanted medical conditions. In this proposed study a wireless device that acquires physiological signals is developed to ease and improve quality of life. The device has to be wireless in the modern technology because nobody wants to stay connected to tangle of cables while doing everyday activities. Therefore, the device which is developed includes Zigbee technology for wireless communication. The working principle of the device is to take data from a heartbeat and a temperature sensor and transfer it to the microcontroller. After the microcontroller processes the incoming data via the program that is developed, the data is transmitted by Zigbee wireless protocol. After that computer takes the incoming data and transfers into the program that is developed by using java. It is a long lasting wearable device because Zigbee technology provides wireless data transfers with very low power when compared with other available technologies.
