In this work, we develop high flexible and compressible porous PDMS structures by using sugar cubes as templates. Force sensitive resistor (FSR) sensors were fabricated by the filtration of the CNT solution inside the porous structure of PDMS. We found that sufficient acid treatment can increase the adhesion between CNTs and PDMS. FSR sensors respond the applied pressure and compressive strains by high linearity (R2>0.97) and sensitivity (GFs>2) with a reliable manner.
