Rfid tags in contrast are low cost and disposable and can be printed in rolls of individual stickers similar to barcode tags.
Diaper users include infants elderly disabled individuals and hospital patients.

These sensors are designed to be reusable requiring a caregiver to remove and clean the sensor before attaching it to each new diaper.
In addition to two way audio and a wide angle lens the camera also tracks humidity.
Moisture sensors could ping a clean signal periodically then initially sense an event and trigger the conductive elements to assess what exactly the diaper is packing.
