A low power pervasive RFID identification system for medication safety in hospital or home tele-care

The current mobile RFID readers in size of mobile phones cannot cover sufficient reading distances and not very practically usable in health-critical cases like infectious diseases. In addition, the operation time is not always enough for care personnelpsilas daily visits. The main reasons for reading distance limitation is the propagation power required for wake-up and data transmission of RFID tags, which needs accordingly bigger antennas and is very power hungry. This paper describes a concept to overcome these limitations using a very low cost so-called ldquoRFID Power Generatorrdquo at patientpsilas bed-level as signal propagation power source for mobile RFID readers. Furthermore architecture and workflow of several medication safety services are introduced using this concept.
