Structured elastomeric submillimeter films displaying magneto and piezo resistivity

ABSTRACT Structured elastomer films (100-150 μm) presenting piezo and magneto resistance are described. The films are composites of filler particles, which are both electrically conductive and magnetic, dispersed in an elastomeric matrix. The particles consist of magnetite (6 nm) grouped in silver-c...
