paper thin force sensors?

[Bill]

Hi all,

I am looking for thin force sensors that can detect a load between 2
non-deformable plates. It seems that all the thin-film force sensors
(like Flexiforce) and FSR (Interlink Electronics) available do not
meet my applications - I am looking to sense forces in the range of 0
to 10 pounds with fairly high accuracy and resolution. For custom
jobs, these companies require you to order some ridiculous
quantity...which is not for me! Any suggestions would be much
appreciated.

Thanks,
-Bill

How thin is thin? There was company developing extremely thing
capacitive force sensors using internal polymer springs. IIRC they ended
up with a couple of different sizes. principle was simple, one plat each
side of the 'spring' which was effectively a small O-Ring. worked up to
loads in excess of 10lbs certainly. But these were not paper thin. hang
On, just been to their website, address below. they are advertising
paper thin force sensors up to 300 pounds. These guys were exceptionally
easy to deal with last time I looked.

How thin is thin?
