Due to the ageing population, real-time and autonomous health monitoring is an emerging priority in ambient assisted living. In this work, a wireless sensor network is proposed for home environments by which the sensors are dualmode radars, enabling concurrent remote localization of a person (i.e., without use of a tag) and fall detection. We elaborate on the network architecture, and in particular...
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...
Radar techniques aiming at health monitoring have been investigated in recent years. The possibility of contactless monitoring human individuals has aroused interest in many applications especially where the use of wearable sensors generates discomfort which not only may affect the results but also imposes a risk factor. Radar technologies represent therefore the new emerging solution to promote 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...
