Conductive Foam Pressure Sensor. Insulator

Ezsynn

Okey, I made pressure sensor but the last thing I need is a sheet insulator.
To wrap around and insulate the sensor.
What to use?

Ezsynn,

Can you be a little more descriptive of your particular sensor application? That might help us provide a better, more informative answer.

I made these from conductive foam, the kind that holds ICs and
prevents their static electricity zapping. It was easy to use two
small circular copper plates. Solder a wire to each plate and lead
it to a Basic Stamp rc circuit. To ensure repeat reliability, choose
the conductive foam that rebounds the quickest. There are several
varieties in use. Wrap the exterior with thin material such as cloth
which is an insulator. If the parts are held in a small tube, like a
pen body, a thick formed wire can act like the supporting active
linkage and push on the foam.

I haven't built one but I would think that you would be able to use some plastic food wrap aka cling wrap.

Something like this
