MIT's "Smart Diaper" alerts caregiver when its wet

1 Share

MIT researchers outfitted a baby diaper with an RFID tag that emits a wireless signal when the surrounding material gets wet. The wetness "sensor" is actually a type of hydrogel that's commonly found in diapers to absorb liquid. As the hydrogel gets wet, it swells and its conductivity increases, triggering the RFID tag. The RFID tags are printed as stickers for around 2 cents each compared to other Internet-connected diapers in development with reusable sensors that cost as much as $40/each. From MIT News:

Over time, smart diapers may help record and identify certain health problems, such as signs of constipation or incontinence. The new sensor may be especially useful for nurses working in neonatal units and caring for multiple babies at a time...

(MIT AutoID Lab researcher Pankhuri Sen) envisions that an RFID reader connected to the internet could be placed in a baby’s room to detect wet diapers, at which point it could send a notification to a caregiver’s phone or computer that a change is needed. For geriatric patients who might also benefit from smart diapers, she says small RFID readers may even be attached to assistive devices, such as canes and wheelchairs to pick up a tag’s signals.

Blockchains are like grappling hooks, in that it's extremely cool when you encounter a problem for which they're the right solution, but it happens way too rarely in real life.

Now that XKCD said so, maybe the last few nerds will stop trying to push #Blockchain.

I'm afraid that those who should take this advice seriously are those who take XKCD ironically.

In practically all of those rare situations where grappling hooks are *a* solution, a better solution exists. Like a ladder, for example.

Some people suspect that it started as a "No, I didn't forget Valentine's Day" excuse that got out of hand.

"Off-by-one errors" isn't the easiest theme to build a party around, but I've seen worse.

This thought has occurred to me many, many times. Usually when trying to remember my own age.
