Flexible TVs, High-Performance Wearable Smart Tech One Step Closer

A printed circuitboard.

A new nanoscale transistor is suited to applications such as flexible televisions and wearable smart technologies.


Researchers at the University of Manchester in the U.K. and Shandong University in China have developed a nanoscale transistor, a device that could be used in flexible televisions, tablets, and phones, as well as in wearable smart technologies.

The ultrafast, nanoscale, thin-film transistor (TFT) is the first oxide-semiconductor-based device capable of operating at a benchmark speed of 1 GHz.

Current TFTs are mostly silicon-based, making them opaque, stiff, and expensive. This development could enable electronic gadgets to become faster, brighter, and more flexible.

University of Manchester professor Aimin Song says the new GHz transistors may enable medium or even high-performance flexible electronic circuits, noting that wearable electronics require flexibility and, in many cases, transparency.

Oxide semiconductor TFTs will also play a critical role in smart homes, smart hospitals, and smart cities, according to Song.
