A trilayer electrochromic PEDOT-based device is shown electrochromically switching in a 0% strain and 30% strain configuration
PEDOT (poly(3,4-ethylenedioxythiophene)) is an electrically conducting and electrochromic polymer that changes colour with the application of voltage between dark blue and close to transparent (light blue). With additives it can be made highly stretchable while remaining conductive. We are taking advantage of these stretchable electrochromic conducting polymers in combination with other stretchable material component layers to develop a low cost, low power and high contrast stretchable electrochromic display for consumer electronics and biomedical applications. We aim for this to be incorporated into on-skin multifunctional wearable devices for more seamless conformability with motion and integration with the body.
