pressure sensor

[polkendy]

Hi folks

I need help in finding a pressure sensor that can be used to measure in-shoe foot pressure. Its for a football boot design project in which im aiming to reduce the pressures on the foot but need to test prototypes and they would be very useful.

Any ideas where i could get hold of some??

If not any ideas of the components in would need to make one??

hi,
There are pressure sensitive resistive devices, 'Quantum Tunnelling Composite Pills' QTC.
They are small pads about 4*4*1mm thick. [thin enough to fit in a boot]

The resistance of the pad can change from 10megOhm to 10ohms with applied pressure.
Force Range 0 to 100N
Lifetime > 10^6 compressions.
Max current 10Amp, Op Voltage 0 to 40V.
Op temp range -20 thru 120C
Humidity 0 to 100% [ ideal for a sweaty environment]
