Mini wireless battery powered pressure sensors

[Slind]

Hi there,

I'm looking for small wireless battery powered pressure sensors. Disruptive Technologies are working on some but they aren't on the market yet. Are you aware of something similar?
For all I care they can be a little bit bigger, don't need to hold 10 years and I especially don't need all the software/cloud behind it.

@slind what's your definition of small?

Small enough to be used with doors (their rubber seal).
