Micropatternable flexible elastomeric nanocomposites find application in sensing biomechanical strains and biopotential signals [1-5]. While many polymers have been used to fabricate flexible MEMS polydimethylsiloxane (PDMS), a silicone based elastomer, has been widely used because of its biocompatibility, low cost, low toxicity, high oxidative and thermal stability, optical transparent, low permeability to water, low electrical conductivity, and ease of micropatterning [6-15]. Previously, we had demonstrated fabrication of various PDMS based micropatternable nanocomposite polymers which are either electrically conductive and magnetic in nature [16-17].

We have developed improved electrically and thermally conducuctive micropatternable PDMS based nanocomposite polymer containg milled carbon fibers, prepared by ultrasonically assisted processing technology. The prepared nanocomposite microstructures show interesting resistance hysteresis loop. This paper also discusses the underlying mechanisims that are responsible for resistance hysteresis loop.
