MIT engineers give RFID tags chemical-sensing capabilities
Engineering specialists from MIT have devised a way to make RFID (radio-frequency identification) tags more reliable and pick up on chemicals in the surrounding environment -- without needing the typical battery.
As far as wireless technologies go, radio-frequency identification (RFID) is one of the oldest. Patented in 1983 by the late British inventor Charles Walton, RFID made it possible for new, cutting-edge tech such as near-field communication (NFC) to e...
