Electrical resistance change of PG foams and A-PG foams under mechanical deformation.
(a) The resistivity measured on foams was ~100% change at a strain amplitude of 80%, and the initial resistivity-strain relationship is near linear. (b) Variation of normalized resistance as a function of tensile strain.
