Abstract

We comparatively study the performance of flexible strain sensors based on carbon nanotube (CNT)-Polydimethylsiloxane (PDMS) nanocomposites with different concentrations of CNTs. The semiconducting CNTs with high intrinsic gauge factor were employed for the sensor fabrications. A percolation network with a lower CNT concentration shows higher resistance changes in response to applied strains compared to those network with a higher CNT concentration. However, from a stability point of view, a lower concentration percolation network shows much worse characteristics than does a higher concentration percolation network. For the analysis of our observations, a 2-D percolation-based numerical model based on the Monte Carlo method was employed to understand the electrical and coupled electromechanical behaviors of CNT-PDMS nanocomposite strain sensors.
