Resistive sheet

cured, wet concrete and typical soils & clays have resistivities in the

100 ohm-m range.

In that case, try the conductive anti-static foam sheets (24 inch by

12 inch by 0.25 thick) that Jameco carries; part 13864 for $9.29 ea or $8.35 each @ 5. They roll it up for shipping. Measured resistance across diagonal with probes close to the corners, is about 8K.

Not flexible; brittle. Also not usually available in sheets.

Please read the frigging spec sheets, on the links provided, before commenting.

Polymer materials are available in sheets, rolls, or injection molding pellets.

The problem with filled polymers is dimensional instability - hence their use in pressure and humidity sensors and a restricted environmental range - and problems using them as a heaters. When deposited in thin fims on mechanically rigid formers, they have more common applications.

The usual method of producing conductive/resistive polymer is to carbon fill, but just try to locate a vendor of sheet stock with resistivity lower than the typical ESD dissipative ranges......

Great. Thanks John. The silicone is particularly intriguing.
