Flexible Fiber LEDs made with perovskite quantum wires should enable advanced wearable displays and other technologies

Yesterday, researchers from the School of Engineering of the Hong Kong University of Science and Technology (HKUST) provided exclusive quotes on the release of their study titled Full-color fiber light-emitting diodes based on perovskite quantum wires to TechXplore, where they insist that their "innovative approach (perovskite wiring) for fiber LEDs opens up new possibilities for fabricating unconventional 3D-structured lighting sources, paving the way for advanced wearable display technologies". This quote was provided by the HKUST Department of Electronic & Computer Engineering and Department of Chemical & Biological Engineering Professor Fan Zhiyong, who also served as lead of the research team for the project's duration.

The project's primary purpose was to find a better way to make fiber wire LEDs, also called fi-LEDs. The issue with making these flexible LEDs has always been a matter of material, which often causes uneven or inefficient light emission. Using metal halite perovskites with a porous alumina membrane to create quantum wiring seems to be the correct way to mitigate these downsides, resulting in a series of full-color fi-LEDs. These fi-LEDs are already in such a condition that they should be suitable for textile lighting applications.

With "bendable, stretchable, twistable, and waterproof" fi-LEDs now in play, the future for wearable applications is looking quite strong— though, of course, any practical clothing brand may have second thoughts about integrating fiber LEDs into its clothing. Outside of scenarios where specific uniforms or outfits are in play (a la scuba diving), it's unlikely that fi-LEDs will introduce a new era of sci-fi fashion trends— but potential practical applications do seem interesting.

    I could see this replacing neon lights as could likely get same effect w/o the downside of neon element.
