“Green RFID”: an enabling technology towards the Internet of Things (IoT) world
A brief description of the present and future scenario correlated to ICTs will be illustrated. Environmental implication of present societal and technological trends will be analyzed in order to address the most important and relevant issues. On the basis of this analysis, RFID, as an enabling approach compatible with the described scenario, will be introduced and motivated. Future environmentally friendly technologies and architectures, suitable for “green RFID” implementation, will be introduced, namely: paper printed circuits, organic materials, chip-less tag, harmonic RFID, autarkic sensor nodes, CNT based RFID gas sensors and so on. Some application proposals will be reported in order to illustrate the groundbreaking vision enabled by “green RFID” approach; in particular it will be shown the potentiality of the “green RFID” technologies toward the development of a new concept of indoor localization systems and assisted paths as well as the capability of massive use of green RFID tags for extensive monitoring and for measurements in harsh environments where high numbers of wireless sensors is needed without the possibility to recover them. These example applications will be used to draw final considerations about future developments, challenges and perspectives. It is worth noticing that this topic is, at present, the main one of a book recently committed to myself by Cambridge Press, entitled “Green RFID”, to be published in 2013.
