ABSTRACT:
An RF tag (20) includes a low profile battery power source (22). The RF tag includes an electrically insulating substrate 21, an RF transmitter (24) on the substrate for transmitting a predetermined identification code, and the battery (22). The battery includes a first pattern of conductive material to form a planar anode structure (48) and a second pattern of conductive material on the substrate to form a cathode structure (50). A protective layer (92) overlies the substrate. The protective layer includes an opening (94) to expose the anode and cathode of the battery to permit an electrolyte to be applied to the anode and cathode for completing the formation of the battery and to provide electrical energy to the RF transmitter. A manufacturing apparatus (60) is also described which permits the RF tags to be manufactured in a low cost, reel-to-reel, basis. Also described is a dispenser (100) for activating and dispensing the RF tags one at a time at a point of use.
