New technology will allow you to print phones and other electronics directly on clothes

A new version of spaser technology (amplifying surface plasmons through forced radiation) could make mobile phones so compact, efficient, and flexible that they can be printed on clothing.

A team of researchers from Monash University has managed to simulate the world’s first spaser made entirely of carbon.

The spaser is actually a nanolaser. It emits a beam of light through the vibration of free electrons, instead of the rather cumbersome process of emitting electromagnetic waves from a traditional laser. The carbon structure of the new spaser gives it many advantages.

The use of carbon (as opposed to gold or silver nanoparticles and semiconductor quantum dots of traditional spasers) makes the new device more durable and flexible and allows it to operate at higher temperatures.

Spaser-based devices can be used as an alternative to modern transistor systems such as microprocessors, memory and monitors.

The material for their spaser, researchers from Monash University chose graphene and carbon nanotubes. They are more than a hundred times stronger than steel and can conduct heat and electricity much better than copper. Their research has shown for the first time that graphene and carbon nanotubes can interact and transfer energy to each other through light. These optical interactions are extremely fast and energy efficient – and therefore well suited for applications such as computer chips.
