Abstract

The present invention includes scalable and cost-effective auxetic foam sensors (AFS) created through conformably coating a thin conductive nanomaterial-sensing layer on a porous substrate having a negative Poisson's ratio. In general, the auxetic foam sensors possess multimodal sensing capability, such as large deformation sensing, small pressure sensing, shear/torsion sensing and vibration sensing and excellent robustness in humidity environment.
