Nothing's free. I want low cost, not free.

The abstract of that article [you sent me] seems to say my idea DOES work.

I need those vibrations to be communicated to a remote receiver (less than 100 feet away) and be uniquely identifiable.

What part am I missing?

So, that would mean a remote device plugged into the PC that picked up the 1.9 GHz. And that receiver would receive all signals from roughly 100 widgets, each with is own device attached?

OR, must there be some form of receiver on each device?

So long as you are less confused than I am, you certainly can help ;)

I see...it says.

Furthermore, a 1 cm3 generator has been used to power a custom designed 1.9 GHz radio transmitter from the same vibration source.

So, I have to think I am not the first to need the vibration from a widget, and want to use a piezoelectric vibration sensor to power the transmission of that vibration. Can't I then use an active RFID which transmits vibration? Once it gets juice, it seems it would be ready to transmit. Please comment.
