A study demonstrates elimination of piezoresistivity in flexible conducting polymers for accurate temperature sensing under dynamic mechanical deformations. The same structural change is co-related with a switch in the polarity of polyaniline- poly(2-acrylamido-2-methyl-1-propane-sulfonic acid's (PANI-PAAMPSA) GF from positive to negative. The study demonstrates the construction of simple sensors with near-zero GFs by combining PANI-PAAMPSA with another conducting polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), which retains its positive GF after DCA treatment.
