Radio Frequency Identification Device (RFID) is the name given to the wireless, radio wave technology that allows for a small RFID chip to be embedded in any physical object and uniquely identified by an RFID reader. With an unlimited amount of possibilities for connected devices we are now seeing consumer packaged goods, animals, waste management systems and even humans tagged with RFID chips. RFID is not a new technology and has passed through many decades of use in military, airline, library, security, healthcare, sports, animal farms and other areas. Industries use RFID for various applications such as personal/vehicle access control, departmental store security, equipment tracking, baggage, fast food establishments, logistics, etc. The increasing ageing population around the world and the increased risk of falling among this demographic, challenges society and technology to find better ways to mitigate the occurrence of such costly and detrimental events as falls. The most common activity associated with falls is bed transfers; therefore, the most significant high risk activity. Several technological solutions exist for bed exiting detection using a variety of sensors which are attached to the body, bed or floor. In this paper, present and evaluate a novel method for mitigating the high falls risk associated with bed exits based on using an inexpensive, privacy preserving and passive sensor enabled RFID device.
