Abstract

Patients in bed should be monitored continuously. Because of their tiredness and ill health, they may fall down or may be injured severely by dashing on the walls etc. So a dedicated nurse should watch them day and night. Innovative technology approaches have been increasingly investigated aiming at human-being long-term monitoring. In this project, a complete system for contactless health-monitoring in home environment is presented. It used a Radar technique to monitor the patient. The radar system consists of an IR transducer pair. The signal from the radar will be changed according to the position of the patient. If there is any deviation from normal position, the signal will be different for different actions. According to the signal from the sensors, the software analyses the position of the patient and accordingly the status of the patient. Thus it is very useful to find out the position of the patient without any dedicated nurse inside. Future work is to combine multiple sensors in a wireless sensor network configuration, in order to monitor multiple persons and to increase the accuracy and coverage area, beyond one room.
