What a neat idea! Sounds nice and compact and simple to build too.
Do you think it would also be viable to use a soft NON-conductive foam
and then measure the capacitance instead of the resistance to work
accurately with lighter pressures?

Actually this will work better. I built a grid sensor using (...) (27 years ago, 11-Apr-97, to lugnet.robotics.handyboard)
