C4.2 - Large-Area Wireless Sensor System for Ambient Assisted Living

A. Steinhage, C. Lauterbach & A. Techmer
We present a large-area wireless sensor system underneath the floor covering which is based on smart textiles. Typically 32 sensors per square meter invisibly installed underneath soft or hard floor coverings measure the change of capacitance induced by people walking across the floor such that the location and the state of persons can be detected. The system supports applications in many domains such as security, energy saving, comfort, entertainment, marketing and robotics. Within this paper...
