Improved electromechanical performance of the Ag film/PI substrate (or Ag film/thick PET substrate) systems under an electrical current. (a) Comparison of 400 nm Ag/PI substrates and 400 nm Ag/PET substrates under an electrical current of 0.3 A. (b) Stretchability and its loss as a function of electrical power for 400 nm Ag/PET substrates and 400 nm Ag/PI substrates.
