Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...

Liquid metal controlled by low voltage reversibly switches color and infrared response in nanoscale surfaces, enabling low power reflective displays, sensors, and optical security features. (Nanowerk ...

Henry Ford famously said a customer can have a car in "any color that he wants, as long as it is black." But black on self-driving cars could be deadly. That can help explain why the May Mobility self ...
