Imagine using your coat to look through the Internet, send and receive messages, and even read a map. Yes, you read that correctly—your coat.

It may sound silly, but it’s something scientists are working on. Researchers at Shanghai’s Fudan University have made a new type of cloth that can be used as a digital display(显示屏).

Professor Peng Huisheng and his team have spent more than 10 years trying to make “digital cloth”. After testing different combinations, they chose two materials that worked: silver-plated yarn(镀银纱)that can light up and a kind of thread(纺线)that conducts(传导)electricity.

The results have been admirable. It’s not only wearable and foldable, but also washable. After being put through 100 wash-and-dry cycles in a washing machine and folded 10,000 times, the cloth remained almost unchanged.

Peng believes that the new cloth could be used for many things. For example, it could allow drivers to view a GPS map on their arms while they drive around. It could also help people communicate better if they have language barriers(障碍)or disabilities.

In one test, Peng’s team collected brainwaves from volunteers who had either been playing a game or meditating. The brainwaves were then translated into messages like “anxious” or “relaxed” and shown on the cloth. This could help hearing-impaired and speech-impaired people “talk” to each other in the future.

“We hope that new materials will shape next-generation electronic devices by changing the way we interact with them,” said Peng.
