Is anyone here an expert on RFID sensors? Especially RFID pressure sensors/load cells?

Need some advice and finding it amazingly difficult to get useful information online...

Sorry dude. It's tough to find anything on them. I listened to a guy from Texas a&m talk about grainflow and moisture sensors. If you cant find anything else let me know and i'll try to find my notes.

What are you putting them on?

It's another way for the government to track you/teedubya

I'm looking for CHEAP RFID load sensors with a smallish (1"-4") form factor. Not really finding anything.

In theory, you should be able to cheaply manufacture very simple piezoelectric load sensors that use the load change to create enough charge to transmit a high frequency RFID signal. But so far, I'm coming up empty.

Throw in the word "hobby" in your google searches.

Here is one I found:

I'd guess the cheap part will come when you are ready to buy in bulk, but maybe this will give you a lead.
