Composite conductive foam

An apparatus, comprising:

• a material including a non-layered mixture of:
• a polymeric foam, and
• conductive fillers disposed in the polymeric foam;
• at least two probes in contact with the material;
• and
• a voltage detector coupled to at least one probe of the at least two probes,
• wherein, the material exhibits a decrease in electrical resistance and generates an electric potential when deformed.

An apparatus, comprising:

• padding including a non-layered mixture of:
• a polymeric foam, and
• conductive fillers, the conductive fillers including conductive fibers;
• at least one probe in contact with the padding;
• and
• a voltage detector coupled to the at least one probe,
• wherein, the padding exhibits a decrease in electrical resistance and generates an electric potential when deformed.
