Pressure sensitive electrochromic device and method of fabricating the same

A method of fabricating pressure sensitive electrochromic device, comprising steps of:

• providing a first substrate and a second substrate, at least one of which being made of a flexible material;
• forming a pressure sensitive layer on the first substrate, comprising:
• forming a first conductive layer on the first substrate;
• forming an insulative layer on the first conductive layer, and a plurality of conductive grains distributed in the insulative layer;
• and
• forming a second conductive layer on the insulative layer;
• forming a third conductive layer on the second substrate;
• depositing an electrochromic layer on the third conductive layer;
• assembling the first substrate and the second substrate so that the electrochromic layer is disposed between the third conductive layer and the pressure sensitive layer;
• and
• providing an external circuit across the first conductive layer and the third conductive layer.
