I did look back through the archives  - there was a conversation about those curious QTC pills but nothing I could find about 'position sensitive pads'. No bother.

The various 'force sensing resistors'  on the market now are definitely an option - but right now I'm looking at just using piezos and coming up with interesting ways to mix/differentiate the voltages they produce to try and emulate 'position'.

As always - the replies I got have given me *loads* of food for thought and some good places to start researching.

Thanks to everyone.
