Figure 2. Electrical performances of LIG-based strain sensor. (A) The normalized resistance versus the tensile strain for the LIG-PI sensor; (B) the normalized resistance versus the tensile strain for the LIG-PDMS sensor; (C) the normalized resistance values of the LIG-PDMS sensor during tensile experiments with different strain rates; (D) relative change in resistance under repeated loading and unloading of 20% strain for 200 cycles.
