The Widget Revealed May 18, 2011

Yesterday, NDSU filed the provisional patent on my widget.  This means I am provisionally an inventor, according to the USPTO.  I think that no one can ever again question my engineer cred.

Okay, not really.  What it really means is that I can talk about it now without worrying anyone else will take the idea.  However, I also have a paper in the works (which, once I finish fighting with LaTeX, will be submitted shortly), so I won’t bore you with the details.

The widget, if you’re curious, is an UHF RFID tag that works on metal, using the metal surface for its antenna, and it’s about 2 mm thick.  (Commercial tags for metal are about 2-3 times this thick, minimum.)  The goal we’re working toward is, of course, a flexible, paper-thin antenna that will work on metal.  I actually think that’s doable, but I can’t say for sure how long it’ll take.  (And I’d be wrong if I guessed, anyway.)

So that’s the gist of it.  Details will be in the paper…whenever and where ever I manage to get it published.

Congratulations!

I’m just curious but how much of a hassle was it with the university’s tech transfer office? I’ve always had a bitch of a time with that…

Actually, people are pretty poor conductors because they have such a high dielectric. However, there is actually a lot of stuff being done to integrate antennas into clothing.
