Fall incidents are considered one of the most dangerous hazards for elderly people. In this regard, radar techniques can be used to develop a long-term fall detector system in home environment. The key relies on measuring and assessing the different changes in speed experienced during a fall and a normal movement. In this paper, the accuracy of a fall detector based on Doppler radar is analyzed comparing...
The elderly population has been steadily increasing worldwide. This situation has resulted in a growing need for healthcare approaches that emphasize routine long-term monitoring. Monitoring is of primary interest in the home situation in cultures where elderly do not live with relatives. In recent years, wireless technologies have been investigated aiming at health monitoring. They represent the...
An optimization of a Stepped-Frequency Continuous Wave (SFCW) radar for contactless fall detection and tag-less localization is presented and discussed. Wideband antennas with different topologies are investigated to solve the backscattering problem, which strongly overwhelms the signal when the radar is operated on a wall. Experimental evaluations with a real human subject indicated accurate detection...
<?Pub Dtl?>Innovative technology approaches have been increasingly investigated for the last two decades aiming at human-being long-term monitoring. However, current solutions suffer from critical limitations. In this paper, a complete system for contactless health-monitoring in home environment is presented. For the first time, radar, wireless communications, and data processing techniques...
