TECHNOLOGY The touch- responsive technology is said to be around 100 times thinner when compared to the touch screen materials that are currently existing. The touch- responsive technology is said to be having the flexible feature and it can be rolled up like a tube. This ultra- thin and ultra- flexible electronic material have been created by the researchers from RMIT University, UNSW Monash University and ARC Center of Excellence in Future Low- Energy Electronics Technologies (FLEET). A thin film that is commonly found in the touch screens of the smart phones has been used by the team of researchers from the RMIT University, UNSW Monash University and the ARC Center of Excellence in Future Low- Energy Electronics Technology in order to create the ultra- thin and ultra- flexible electronic material. 98 The material from the smart phone touch screens had been shrunk to 2D from 3D with the usage of liquid metal chemistry and the sheets are said to be compatible with the technologies that are existing. It has been said that the material can be manufactured using the roll to roll (R2R) processing as the material is flexible enough to be rolled up like a tube and therefore the material can be considered to be like a newspaper. The touch screens of most of the smart phones is said to be made up of indium- tin- oxide (ITO) which is a transparent material. The transparent material is brittle but is very conductive and based on it, a new kind of automatically thin indium- tin- oxide (ITO) has been created by the team which can bend and can be twisted without breaking. The material that has been produced by the team is said to be cheaper and easier to be produced that the touch screens that are currently available. WWW.WISHESH.NET | FEBRUARY 2020 The team has made use of a liquid metal printing approach in order to create the material where in the alloy turns into liquid when the the indium-tin alloy is heated to 200 degrees Celsius.The liquid alloy material is then rolled over a surface which prints off the nano- thin sheets of the indium- tin- oxide. The three dimensional nano sheets that are currently available in the touch screens of the smart phones is said to have the same chemical makeup as the standard indium- tin- oxide but the crystal structure is said to be differing from the material that has been created by the team. The manufacturing of the touchscreens that are currently available are said to be slow, energy- intensive and also expensive. The availability of a vacuum chamber is also required for the current manufacturing of touchscreens. The new method is said to be cheaper with no need of any specialized equipment. The
