Abstract
A deployable acoustic wave RFID/biosensor assembly has at least one protective layer, and an acoustic wave RFID/biosensor within the protective layer or layers. The acoustic wave RFID/biosensor includes an acoustic wave device, a biolayer mounted on the acoustic wave device, an electric circuit operable to actuate the acoustic wave device, and a fluidic chamber associated with the biolayer. In use, the fluidic chamber contains fluid which, if a predetermined substance to be sensed is present, operates to modify the biolayer which in turn affects the operation of the acoustic wave device. Protective fluid is provided within the protective layer or layers substantially surrounds the acoustic wave RFID/biosensor to protect the acoustic wave RFID/biosensor from damage when the RFID/biosensor assembly impacts a target and to protect the biolayer from deterioration during storage and use.
