  • Electrochromic touchscreen
    Patent number: 8907918
    Abstract: The present invention relates to a touchscreen, comprising an electronic visualization structure made of a deposition of layers of: electrically conductive material; on which is deposited electrochromic material; on which is deposited electrolyte material; on which is deposited electrochemically active material, on which is deposited electrically conductive material, wherein the electronic visualization structure is simultaneously an electronic touch detection structure, which touch detection depends on the continuous application of a modulated electrical stimuli; and operates based on variations in the electric capacity of the electronic structure.
    Type: Grant

  • Electrochromic device and method for producing same
    Patent number: 8773747
    Abstract: The present invention relates to electrochromic devices and methods for functionalizing cellulose-based materials, in production and post-production stages, in order to obtain solid-state electrochromic devices. The invention is in the field of electrochemistry. These functionalized cellulose-based materials have typical electrochromic characteristics, specifically the capacity to change the oxidation state, leading to a modification of the physical properties, shown by a color change when exposed to an electric potential difference, being this color change reversible. The color remains in the absence of any electric stimulus, demonstrating a memory effect.

  • ELECTROCHROMIC WO3 NANOPARTICLES, A METHOD FOR THEIR PRODUCTION AND INK USING SAID PARTICLES
    Publication number: 20140139576
    Abstract: Tungsten trioxide (WO3) nanoparticles are synthesized via a sol-gel route using metallic tungsten as precursor and printed on a flexible electrode using inkjet printing in order to build solid-state electrochromic cells. A method for separate control of different spectral regions of the electrochromic device (near infrared and visible) is disclosed.
