Active RFID Europe

Sensor systems used to be an esoteric subject concerned with such things as life support systems in hospitals. However, the prospect of ubiquitous sensors is becoming a reality, saving lives, improving the quality of life of the disoriented elderly, coping with natural disasters, and much else besides. Now there is even a merging of RFID and sensing, with location of items using RFID triangulation and more sophisticated techniques, and some RFID technologies where sensing is a property of the chip rather than an add-on. For instance, Surface Acoustic Wave (SAW) tags can inherently sense temperature and strain but are used for RFID as well.
