Bedside patient monitoring by NFC

The application of NFC for medical data collection is introduced in this research in order to reduce the process of vital signs measurement including heart rate, blood pressure and body temperature. By deploying a smartphone, all measured signals and records can be collected automatically via RFID chip from patient's beds. The proposed system is controlled from the smartphone through Android SDK by transmitting radio frequency to the target RFID chip and communicates with the microcontroller via RS232 serial port. All data are retrieved back and displayed in the smartphone. The microcontroller has EEPROM memory for recording all measured results continuously. This system improves the patient data collection process by reducing time, increasing the accuracy and easy to use. The results show that the percent of accuracy is about 90%. The application can show result correct and successful.
