Researchers develop highly flexible NFC circuits using transparent film based on calligraphy paper

 Researchers at the University of Science and Technology of China in Hefei have developed a pliable high-strength transparent film and demonstrated how it can be used to create NFC circuits that can still be read even after being folded or bent and could be integrated into flexible electronic and optical devices.

The researchers used the multiscale film as a substrate to fabricate a near field communication (NFC) circuit. The film integrated with the NFC circuit not only exhibited high transparency and high haze, but also had excellent flexibility.

Even if the film was severely bent, the information written in the film could still be read quickly and accurately by the smartphone, according to the researchers.
