By using an electric stimulus, electrochromic coatings can change colour.
The material’s oxidation state changes in response to this stimulation, changing the material’s colour. Colour intensity and coating transmission can be adjusted based on the degree of oxidation or reduction.
To control the movement of light, electrochromic materials are employed. As smart windows or mirrors, these apps are used.
Applications include glare-free automotive rearview mirrors, intelligent eyewear, and optical data and storage systems.
There are several different types of organic electrochromic materials.
The Global Electrochromic coatings market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Plans to Develop Electrochromic Applications for Ophthalmic Optics in the Extended Reality Market by Meta Materials and PPG have been announced.
A memorandum of understanding (“MOU”) to develop new ophthalmic smart devices, primarily for extended reality (XR) applications, was announced today by PPG (NYSE:PPG), a global paint, coatings and specialty materials manufacturer, and Meta Materials Inc., a developer of high-performance functional materials and nanocomposites (collectively, the “Companies” with META).
The cooperation focuses on creating dynamic dimming capabilities using PPG electrochromic gels, META’s PERfusion technology, and NANOWEB transparent conductive film from META.
For more than 50 years, PG has a track record of developing ground-breaking solutions for the ophthalmic sector and the public who wear prescription eyewear.
PPG is a dependable supplier, and they are eager to deepen their partnership by include PPG’s high-performance chemistries, which flawlessly compliment their exclusive ARfusion platform and provide dynamic optics to their expanding customer base.
PPG and META think that high index, multi-functional, and lightweight smart lenses will make the XR market—an umbrella term for virtual reality and mixed reality applications—more commercially viable.
The collaboration intends to improve PPG’s electrochromic gel in combination with PPG’s UV-curable optical monomers to deliver improved dynamic dimming capability by utilising META’s ARfusion patented technology with ultraviolet light for curing.
For the first time, these materials are being blended, and it is anticipated that this will result in more affordable and environmentally friendly manufacturing that will benefit everyone along the supply chain, from the manufacturer to the consumer.
High-brightness ambient lighting, like that found outside on a sunny day, is a major obstacle for XR eyewear developers to overcome because turning up the display power in these circumstances drastically reduces battery life.
Dynamic dimming should make a display that is easier to read while using less electricity.
