CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn the future, the need to identify and sense objects through ultra-low-power or zero-power communication mechanisms will be more crucial than now. Backscattering-based radiofrequency identification (RFID) technology could still play a major role through the possible implementation of low-power identification (ID) and communication directly over other technologies.
