• a tag comprising a chemical or biosensor coupled to an ADC may be incorporated within a patient garment for the purpose of detecting environmental factors associated with the occurrence of pressure ulcers.
• Other tags having chemical or biological sensors may be used for purposes such as detecting metabolic markers in saliva, detecting alcohol in breath or saliva, detecting malodorous compounds in air samples.
• the system tag may be subdivided into portions. One portion may contain the antenna, the ADC and the chip, the other portion may contain the sensor. The two portions of the tag may be disposed with the sensor exposed to the functional environment of an absorbent article, and the antenna, ADC, chip portion removed from exposure to the functional environment of the article. The antenna, ADC, chip portion may be made removable and therefore reusable as well.
• conductive hook and loop fasteners such as are available from APLIX Inc., of Charlotte, NC, may be used to create an interface between the functional environment of the article and the exterior of the article.
• the attachment mechanism between the article, sensor and the removable tag to enable conductivity can be hook & loop, compression (e.g.
• the senor may be fabricated as an assembly in electrical contact with the conductive hook and loop pads which in turn are disposed upon an exterior surface of the article.
• Matching pads may be incorporated as part of the assembly of the antenna, ADC, chip assembly and the two respective assemblies may be united using the matching hook and loop pads for operational use of the tag.
• the more costly antenna, ADC, chip assembly may be rendered reusable thereby reducing the overall cost associated with using the system with a number of respective disposable articles.
• the respective assemblies may be formed using conductive adhesive, such as is available from MG Chemicals, of Surrey, B.C., Canada to affix the electrical leads of the respective portions of the tags to their respective hook and loop fastener pads.
• a system 1000 comprises an absorbent article 300, and an interrogator 200.
• the absorbent article 300 comprises a tag 100.
• the tag 100 comprises a sensor 110, and a removable portion 105 including an analog to digital converter, 120, a chip 130, and an antenna 140.
• the interrogator 200 comprises a sensor 210, a power source 220, an antenna 230, an analysis element 240, a display element 250, and a network link 260.
