Piezoresistive behavior in terms of variation of compression stress and electrical resistance for the systems of (a) TPU/MWCNTs with D geometry, (b) TPU/MWCNTs, (c) TPU/GE, and (d) TPU/(MWCNTs-GE) with G geometry. All systems have 60% porosity and are submitted to compression loading/unloading cycles of up to 8% strain.
