“…A typical use case is in detecting whether the patient leaves the bed such as to go to the toilet. Current solutions usually rely on a floor mat placed next to the bed [1] or a proximity sensing deployed with ZigBees [6]. In other related research, pressure sensitive non-contacting electrodes have been applied under the bed to extraction vital signs, such as heart rate and respiration from the recorded ballistocardiographic (BCG) [16].…”

In this research, we present a proof-of-concept Do-It-Yourself (DIY) bed sensor mat that is capable to detect five user postures, including: Supine position, Prone position, Lateral position (left), Lateral position (right), and Sitting. Our prototype incorporates two types of sensors: Pressure Tiles and Capacitive Sensing. To gain an impression on the accuracy, we conducted a study with 11 participants and developed a machine learning model showing accuracy of 85% for an unknown user. In fact, nocturnal postures extend to a third of ones lifetime and therefore, a posture detection can be particularly interesting. Enabled application scenarios include pressure ulcer prevention, bed-exit intention detection, diabetes detection, and sleep apnea mitigation.

“…However, this method has drawbacks including high cost of equipment for handling millimeter-wave radar, and the fact that the detection of drowning may be delayed by the movement of only hands. The third type indirectly monitors the condition of bathers using electromagnetic waves, an example of which is a care recipient monitoring system using RFID tags [7]. In this RFID tag based methods, the RFID tags and antennas have to be installed in the both sides doors and other equipment in the bathroom, so the installation of the system is complicated.…”
