Thank you. I know Interlink (their pressure sensors are used e.g. in
R2M/A-198) and also Infusion Systems. But as far as I know they do not offer
three-dimensional XYZ sensors and the Infusion Systems products are very
expensive. One would have to stack two two-dimensional square shaped sensors
(X+Y) and a pressure sensor (Z). This leads to a poor sensitivity from our
experiences. Especially the second (lower) position sensor becomes much less
sensitive than the upper one. I'd prefere an all-in-one sensor.

I did not know Tactex. Their website looks promising.
