This study demonstrates the piezoresistive behaviour of hyperelastic silicone/CNT nanocomposites for large strain sensing applications. Four different 2D lattices, namely the Hexagonal, Re-entrant, I-shape and S-shape are employed to explore the effect of unit cell architecture on gauge factor. The lattices are produced at three different relative densities (30%, 40%, 50%) to determine the effect of such on piezoresistive sensitivity. Piezoresistive gauge factors of 2.66, 0.61, 4.91 and 0.20 at 125% strain were recorded respectively for each lattice geometry: Hexagonal, Re-entrant, I-shaped, and S-shaped. The results showed the effective sensitivity of the elastomeric nanocomposite auxetic lattices up to 400% tensile strain, far beyond that achieved by extant studies.
