Problems solved by technology

However, film capacitors, lithium coin cells, and traditional rechargeable lithium-ion batteries are too rigid to bend
Therefore, there is a problem that the above-mentioned power supply cannot be applied to RFID tags and non-contact IC cards in the case of bending the tags and cards

[0119] (RFID tag production example 1)

[0120] Next, a fabrication example of the RFID tag according to the present embodiment will be described.

[0121] as figure 1 An IC card with an RFID tag of the cross-sectional structure shown in was obtained as follows.

[0122] First, prepare a 0.1mm thick cover layer 9b made of PVC; a 0.28mm thick PVC core sheet 8b in which the through-holes 6 for charging wiring and charging terminals 7 are arranged and include The cavity part 10 of 1; the 0.28mm thick PVC core sheet 8a, in which the organic radical battery 1, IC module 2, antenna 3, lead wire 4 and charging wiring 5 are arranged; and the 1.0mm thick PVC covering layer 9a. Thereafter, the cover layer 9a, the core sheet 8a, the core sheet 8b, and the cover layer 9a are laminated together in this order from the bottom, and are thermally crimped (120° C., pressure 2 kg / cm 2 ,2 minutes). As a result, fully made figure 1 IC card shown.

example 2

[0124] as Figure 7 IC cards of RFID tags shown in (a) and 7(b) were obtained as follows.

[0125] Prepare a 0.1mm thick PVC cover layer 9b, which includes an opening portion through which the organic radical battery 1 and small protrusions 11 can pass; a 0.28mm thick PVC core sheet 8b, in which wiring for charging and charging The through hole 6 of the terminal 7, and includes a space portion for accommodating the organic radical battery 1; a 0.28mm thick PVC core sheet 8a, in which the IC module 2, the antenna 3, the lead wire 4 and the charging wiring 5 are arranged; and 1.0mm Thick PVC cover 9a. Thereafter, the cover layer 9a, the core sheet 8a, the core sheet 8b, and the cover layer 9a are laminated together in this order from the bottom, and are thermally crimped (120° C., pressure 2 kg / cm 2 , 2 minutes) to shape into a card. A sealing layer 100 (length 40mm×width 40mm×thickness 0.4mm) comprising a thin-film organic radical battery 1 is fixed to the card so that the b...

Abstract

Disclosed is a RFID tag comprising a light-weighted thin foldable built-in power supply which is reusable by charging. Specifically disclosed is an RFID tag comprising an IC module (2), an antenna (3) and a power supply. This RFID tag has a thickness of not more than 0.9 mm, and the power supply is a built-in organic radical battery having a thickness of not more than 0.7 mm.

Description

technical field [0001] The present invention relates to an RFID tag including an integrated circuit (IC) module, an antenna and a power source, and in particular to an RFID tag including a rechargeable and dischargeable secondary battery as a power source. Background technique [0002] For RFID tags (a common name for wireless devices used for radio frequency identification (RFID), IC cards that are held by a person and communicate with reader / writer (read / write) devices and similar devices using electromagnetic waves are called non-contact IC cards Card. A non-contact IC card basically includes a plastic card and an antenna and an IC module disposed in the plastic card. Supply of power supply, clock signal and the like and input and output of information such as data and instructions are performed between the non-contact IC card and the reader / writer device for the IC card by using electromagnetic waves. [0003] In addition, some non-contact IC cards include a power sour...
