  • Ionic conductive ink and stretchable touch sensors or panels based on the ionic conductive ink
    Patent number: 11634603
    Abstract: An inkjet printable ionic conductive ink for producing a touch sensor device is provided. The inkjet printable ionic conductive ink includes a hydrophilic polymer and an ionic salt, a mixture of solvents in which the hydrophilic polymer and the ionic salt are dissolved therein to form a solution, and a surfactant to render the solution inkjet printable. A method of producing the inkjet printable ionic conductive ink is also provided. The method includes dissolving a hydrophilic polymer and an ionic salt in a mixture of solvents to form a solution, and mixing the solution with a surfactant to render the solution inkjet printable. A touch sensor panel comprising the ionic conductive ink and a method of producing the touch sensor panel are also provided.
