However, looking at the existing paper diapers, even those with wetness display structures still need to actively observe whether the paper diapers have a wetness display at any time. For parents or caregivers, the psychological pressure and burden will be virtually increased.

[0073] Please refer to Figure 1A and Figure 1B , which respectively show a schematic diagram of a coplanar waveguide transmission line structure according to an embodiment of the present invention. The coplanar waveguide transmission line structure 10 includes an impedance matching part 100 and a transmission part 110 . The impedance matching part 100 has an input end 101 and a ground plane 102 , the impedance of the input end 101 is matched with the input impedance of the transmission part 110 . The impedance matching part 100 contains at least three adjacent transmission lines, which are the first short-circuit transmission line 104, the radio frequency signal transmission line 106 and the second short-circuit transmission line 108 in sequence from left to right. These three adjacent transmission lines are respectively composed of several adjacent Composed of metal conductors, from left to right are the first ground conductor 111, the first signal conductor 112, the secon...

[0078] Please refer to Figure 2A and Figure 2B , which respectively show a schematic view of the coplanar waveguide transmission line structure 20 according to an embodiment of the present invention. The coplanar waveguide transmission line structure 20 includes an impedance matching part 200 and a transmission part 210 . The difference between the impedance matching part 200 of this embodiment and the first embodiment 100 is that in this embodiment, the first signal conductor 212 and the third signal conductor 216 are not elongated, but extend in an S shape, and the ground plane 202 Extending on opposite sides of the second signal conductor 214 and respectively coupled with the first ground conductor 211, the second ground conductor 213, the third ground conductor 215, and the fourth ground conductor 217 to form a common ground plane, the first signal conductor 212 is coupled Between the input terminal 201 and the first ground conductor 211 , the first ground conductor 21...

Abstract

A radio frequency (RF) identification tag including a substrate, a planar antenna, an RF chip, a plurality of signal conductors and a plurality of ground conductors is provided. The RF chip receives an RF signal from the planar antenna to generate an identification code. The signal conductors are coupled to the planar antenna. The ground conductors, interlaced on two opposite sides of the signal conductors, and the signal conductors are adjacent to each other and disposed on the substrate to form a coplanar waveguide structure which includes an impedance match portion and a transmission portion. The impedance match portion has an input end coupled to the signal conductors and a ground plane coupled to the ground conductors. The RF chip is disposed between the input end and the ground plane. The transmission portion is connected between the impedance match portion and the planar antenna.

Description

technical field [0001] The present invention relates to a diaper, an absorbent pad and a urine wetness sensing system, and in particular to a radio frequency identification tag with a coplanar waveguide transmission line structure and a diaper, an absorbent pad and a sensing system using the same system. Background technique [0002] Generally speaking, the paper diapers used by babies, or the paper diapers and paper changing pads used by the elderly who are bedridden, have limited mobility, or people in a vegetable state must be changed frequently, otherwise, if the urine is wet for a long time, it will be easy to change. Cause diaper rash or skin disease, more likely to cause risks such as urinary tract infection. In particular, at present, long-term care centers have a large number of caregivers and relatively insufficient caregivers, so it is difficult to immediately and accurately know which caregivers need to change their diapers, resulting in an increased risk of uri...
