Researchers developed RFID diapers that signal when wet

The researchers estimate that a diaper sensor costs no more than a few dozen pennies to manufacture.

Technology could also be developed to detect any health problems such as incontinence or constipation

Researchers at MIT have developed a “smart diaper” that can notify parents when it’s time for a change, writes¬†MIT News.

The diaper uses a moisture sensor, which, when it becomes wet, expands and becomes easily conductive, activating an underlying RFID label that sends a signal to a receiver, which in turn sends a notification to a computer or smartphone.

The technology can be used to signal diaper changes for children who themselves do not call attention when it is time, but instead happily continue as nothing happened. Something that is not good when a wet diaper can cause irritating rashes.

MIT’s researchers estimate that a diaper sensor does not cost more than a few dozen pennies to manufacture.

By extension, the technology could also be developed to detect any health problems such as incontinence or constipation. The diaper sensor would also work for adult diapers used by elderly people who are no longer able to take care of themselves.
