Researchers use graphene to create detachable flexible microLED devices

University of Texas at Dallas researchers and their international colleagues have developed a graphene-based method to create micro LEDs that can be folded, twisted, cut and stuck to different surfaces. The research could help pave the way for the next generation of flexible, wearable technology.

Used in various applications like signage and automotive lights, LEDs are ubiquitous because they are lightweight, thin, energy efficient and visible in different types of lighting. Micro LEDs, which can be as small as 2 micrometers and bundled to be any size, provide higher resolution than LEDs. Their size makes them a good fit for small devices such as smart watches, but they can be bundled to work in flat-screen TVs and other larger displays. LEDs of all sizes, however, are brittle and typically can only be used on flat surfaces. The researchers’ new micro LEDs aim to enable bendable, wearable electronics.

EU-funded ATTRACT consortium presents its support of several graphene projects

The MULTIMAL research project is developing a small device that can be used to rapidly identify malaria parasites using saliva samples, without the need for lab equipment. MULTIMAL is one of eight projects exploring new uses for graphene with support from ATTRACT, a €20 million EU-funded, CERN-led consortium, which has awarded 170 grants worth €100,000 each for one-year proof-of-concept technology projects.

Today’s portable malaria testing kits are “just above flipping a coin,” because they are right only 60 percent of the time, says MULTIMAL principal investigator Jérôme Bôrme. The disease, which the World Health Organisation says killed 435,000 people in 2017 (nearly all of them in Africa), is caused by five species of parasite that can be easily identified in a lab. But treating the disease in remote towns and villages is difficult because of the lack of reliable portable testing kits, explains Bôrme, MULTIMAL’s principal investigator and staff researcher at the International Iberian Nanotechnology Laboratory in Portugal, which runs MULTIMAL in collaboration with the University of Minho.
