Electrochromic

Seeking a passive way to keep buildings cool in hot weather and warmer in the colder months, researchers have developed a new electrochromic shape-shifting material. It switches from solid to liquid and from clear to opaque at set temperatures.

You may have heard of electrochromic windows that can be electronically switched between clear and tinted states. Well, the same technology has been applied to a new material that could both heat and cool buildings, if mounted on their outside walls.

E-waste is a growing problem, so if an electronic component can't be reused or recycled, it should at least be biodegradable. That's where an experimental new electronic display comes in, as it can be composted when no longer needed.

A color-changing film could provide a new and better method of obtaining fingerprints from metal surfaces.
