Step 8: Using the Electronic Diaper

My subject did not cooperate as she refused to have a go with the electronic diaper.  Maybe the robot logo scared her.  It's hard to say.  So, I settled for a simulation. I cut a small slit on the back side of a new diaper and inserted the wetness probe.  I poured 2 ounces of water and the electronic diaper worked it's magic.  It instantly notified me it's time to change the diaper.  Success!

The electronic diaper is not a toy.  It has small parts not suitable for human consumption.  While all precautions have been taken in lieu of safety, the possibility also exists of electic shock.  Ask a certified electronic engineer if the electronic diaper is right for you.

This is a brilliant idea. That said, the buzzer worries me a little. It didn't sound to bad in the video, but if your baby doesn't like the sound, then this is classic negative reinforcement. If your baby loves the sound, then it is positive reinforcement. Probably not healthy either way. If you put in a delay of 1 or 2 minutes, then your baby won't associate the peeing with the noise.
That's so true. What was I thinking!<br> A high-end solution is to have a wireless WI-FI transmitter and effectively send a text to a cell-phone instead of a buzzer like caitlinsdad suggested.<br> I could do this with a <a href="http://www.rovingnetworks.com/Docs/WiFly-RN-121-DS.pdf">wifly RN-121</a>, but it will get really bulky if it isn't already.&nbsp;<br> Maybe one day Huggies will come out with&nbsp;these.&nbsp; Each diaper could&nbsp;<br> have embedded conductive thread where&nbsp;you clip on a&nbsp;SMT board inside a pocket.&nbsp; Like if diapers were not expensive enough already!<br> <br> &nbsp;&nbsp;&nbsp; if (firstiswet) then<br> +&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; delay_1s(120) -- wait 2 minutes&nbsp;<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dobuzzchime&nbsp;<br> &nbsp;&nbsp;&nbsp;
I wonder if you could do it with an RFID tag. Break the circuit on the tag so that it is only functioning when moisture is detected. Then the RFID reader and wireless (or wired) transmitter could be in the crib/stroller/etc.<br><br>BTW, is there enough water in poop for your probe to detect?
I have not worked with RFID and reading about them sounds like a good idea with an active tag. <br> <br>Good question. I'm guessing yes, there is enough most of the time. <br> <br>I think one of these days I'll &quot;install&quot; it during a nap and hope she does not mind when she wakes up. Maybe I can catch that rare moment in the name of science and report back.
Bit of a double edged sword maybe.<br> <br> Now there an Oprah I cant wait for &quot;my dads crazy invention makes me pee myself every time I hear a fire truck, ambulance, police siren etc&quot;&nbsp; LOL<br> <br> A negative sound would be of use in the nappy around potty training time.<br> <br> You could put one in a potty that has a positive sound.<br> <br> The flashing LED is a good idea.<br> <br> Keep up the good work.<br> <br> <br>
That would be great. Then I come out on Oprah riding my antique bicycle! <br>Looked it up, and this stuff is actually patented and a wireless version for seniors is already out. Hm
I'm almost certain the potty with this in it is patented too.<br> <br> Here's a theme tune for when you ride you bike around Oprah's couch. :-)<br> <a href="http://www.youtube.com/watch?v=uoC7kuFV3oY">http://www.youtube.com/watch?v=uoC7kuFV3oY</a><br>
Hi, <br>this is a cool idea!!!<br>but you could do all of this with only one 555, easier with two<br><br>
Ha, it should really tweet a message to the nanny to attend to the diaper change...
Every time a child goes to the bathroom a buzzer goes off and lights start flashing. I can see a pavlovian response later in life. I like it.<br><br>Maybe this could be adapted for coworkers?
Interesting, there are possibilities of miniaturization, more importantly have you tried to get a patent?
Ha, that's fantastic. I think my son and daughter would try to yank it right off though! Be sure to let us know if your test subject ever gives it a try.
Oh, that's hilarious! Thanks for sharing!
