Abstract
An active RFID label is provided in which the antenna also forms the battery for the RFID chip that is part of the label. The antenna can be made of one or both of the electrodes forming a thin-film lithium-ion battery. The RFID chip, antenna and battery can all be placed upon the same substrate, and because the antenna and battery are co-located, the substrate can be made relatively flexible.
