This conductive material (also known as "Velostat" or "Linqstat") is a nice addition for your wearable/sensor hacking toolkit. It's pressure-sensitive: squeezing it will reduce the resistance, so it's handy for making flexible sensors. And it's a lot less expensive than off-the-shelf pressure or bend sensors too! Each order comes with a 28cm x 28cm 4mil (0.1mm) thick piece.
We may fold the sheet into quarters to ship it to you. To remove any hard creases, simply lay flat on a table and put a heavy book on top to flatten it out.
Temparature limits: -45°C tot 65°C
Heat seal : Ja
Resistor: <500 ohm.cm
Surface Resistance: < 31.000 ohm/sq.cm

Pressure-Sensitive Conductive Sheet (Velostat/Linqstat)
The FSR 402 model is a single-zone Force Sensing Resistor® optimized for use in human touch control of electronic devices such as automotive electronics, medical systems, and in industrial and robotics applications. FSRs are two-wire devices.
This woven conductive fabric is silver-plated nylon. Use small pieces for soft switches, plush keypads, capacitive touch sensors, and other textile interfaces.
Z-axis tape is made by 3M, and is used to bond two conductive surfaces together and allow a small (we'd say keep it under 100mA) current to flow through the tape.
