In a research paper published in Nature Materials, the researchers described their new material and its potential applications. The team, led by Sihong Wang and Juan de Pablo, used computational predictions to design and build many different prototypes of the stretchable light-emitting polymers. The resulting materials were flexible, bright, durable, and energy-efficient.

Most high-end smartphones use OLED technology for their displays, as it is more energy-efficient and offers better picture quality than older LED and LCD technologies. However, the materials currently used in OLED displays are brittle and lack stretchability, which limits their potential for flexible displays.

The new material developed by the University of Chicago maintains the electroluminescence of OLED but uses stretchable polymers to create a flexible display. This breakthrough could pave the way for a range of new technologies, such as wearable electronics and foldable devices.

Apart from being used to display information, the flexible material could be integrated into wearable sensors that need light to work. For example, smartwatches shine a light through blood vessels to measure heart rate and blood oxygenation.

The researchers are now focused on improving the device, starting with adding additional colours while also improving its efficiency and performance. With this new material, the possibilities for flexible displays and wearable electronics are endless.
