South Korean Researchers Develop Bendable Electronic Devices

Over the past couple of decades, the world of electronics has been witnessing shrinking electronics devices. However, majority of these are quite similar to those of the 1950s. A group of South Korean researchers and scientists have developed bendable devices that involve the manufacturing of thin films that keep the magnetic and electric properties alive in spite of being highly bent or curved. 

For a rather long time, the manufacturing of flexible devices has been quite challenging and tough because of the materials and substances that exhibit electronic properties are generally quite rigid. Researchers therefore, have addressed this issue by getting together miniscule bits of substances such as silicon, and embedding these in plastics that are flexible in nature. A group of South Korean engineers and physicists have adopted the same technique with a material known as bismuth ferrite, which is a promising material having electronic properties that can easily be controlled with the help of a magnetic field. The opposite is also possible. These types of materials are known as multiferroics that are mostly applied instant on and energy efficient computing. 

The very first step taken by the researchers was the synthesis of bismuth ferrite nanoparticles followed by the mixing of the same in a certain polymer solution. This was followed by the dehydration (drying) of the solution via several stages at rising temperatures in order to create a flexible thin film. The researchers finally concluded that the magnetic and electric properties exhibited by this thin film were way better and much more efficient. Also, the properties remained intact even if the thin film was bent into the shape of a cylinder.
