Or to inform about something. Apple patents ‘electrochromic’ watch band
Apple has patented a watch strap that can change color – the corresponding documentation appeared on the website of the United States Patent and Trademark Office (United States Patent and Trademark Office). As stated in the patent description, the user will be able to customize the color of the Apple Watch band depending on the color of clothing or accessories, the environment, or according to other preferences.
Apple Watch band will be able to change color to match the wearer’s clothing
Also, a “colour-adjustable watchband” can be used to alert the wearer: the color will change depending on the information that needs to be conveyed. For example, the strap could display certain icons and shapes, or even scroll through a text message like a news feed.
From a technical point of view, the color change will provide “electrochromic elements”. The electrochromic layer can be electrically connected to a conductor so that a voltage applied to the conductor is transferred to it. This should result in different colors and color combinations being displayed on the same bracelet. While we are talking about straps made of fabric, which can be woven with electrochromic elements. It is not clear if other materials (silicone, leather or metal) will be used in the future.
