Velostat is a packaging material made of a polymeric foil (polyolefines) impregnated with carbon black to make it electrically conductive. It is used for the protection of items or devices that are prone to damage from electrostatic discharge.[1] It was developed by Custom Materials, now part of 3M.[2]

Due to it's properties of changing it's resistance with either flexing or pressure it is becoming popular with hobbyists for making inexpensive sensors for microcontroller experiments.[citation needed]
