Soon you could talk through a phone printed on your clothing
In an era when just about everyone is running the rat race for the largest screen smartphones, a team of researchers led by PhD student Chanaka Rupasinghe, at the Monash University, Australia, have been working on a new spaser technology that could let us wear our phones someday. Researchers are investigating a carbon-based spacer technology which could allow mobile phones to shrink to a size small, efficient and flexible enough to be printed on clothing.
Spaser is basically a nanolaser, which emits light through vibration of free electrons, unlike traditional lasers that indulge in a very space-consuming process. Enhancing on this property, researchers have used carbon nanotubes and grapheme to make their first of its kind spaser. In their research, the team found that graphene and carbon nanotubes can interact and transfer energy between each other through light, which means it can be used for application like a computer chip. Additionally, it was noted that composition of carbon nanotubes and grapheme makes the spaser stronger than steel and better conductor of electricity than copper.
The carbon-based spaser is more durable, flexible and more eco-friendly. It can operate at higher temperatures, and these properties predict that spaser-based device could mean a future where ultra-thin mobile phones will be printed onto our clothing. However, it should be noted that the research, for now, doesn’t take into account the user experience. Say for instance, what will happen to the phone on your T-shirt when it is washed?
