Velostat, also known as Linqstat, is a packaging material made of a polymeric foil (polyolefins) impregnated with carbon black to make it somewhat electrically conductive.
It is used for the protection of items or devices that are susceptible to damage from electrostatic discharge.
[2] Velostat is a U.S. registered trademark (4,964,564) of Desco Industries Inc. Desco Industries purchased the assets of the 3M Static Control business on January 2, 2015.
For instance, 25 mm2 of 0.2 mm fresh Velostat sandwiched between two electrodes has a resistance around 9 kΩ without any force applied, but only 1 kΩ when 3 Newtons of force is applied.
[4] Velostat's low cost and piezoresistive properties have made it popular for making inexpensive flex or pressure sensors for microcontrollers.
