Paper Abstract

Composites manufactured with networks of carbon nanotubes (CNTs) exhibit piezoresistivity. These composites have tremendous potential for integrated and high sensitivity strain sensing. However, modeling CNT composite piezoresistivity remains a challenge. Prevailing approaches rely on resistor network and fiber reorientation models but are computationally burdensome due to the extreme number of CNTs required to form a percolated network. This research circumvents that limitation by developing an analytical model for CNT composite piezoresistivity in tension. The accuracy of this model is verified by favorable comparison to experimental results in existing literature.
