Rather than carry around your phone, you may soon wear it on your sleeve with nanolasers that are currently under development. A spaser, which is basically a laser on the nanoscale, could revolutionize cell phone technology by making it so small that phones could be printed on clothes. The spaser would replace traditional transistor-based devices like microprocessors, memory, and displays and would allow the technology to become miniature by comparison. Plus, these spasers would be made out of graphene and carbon nanotubes, which are more resource and eco-friendly than their current counterparts.

Researchers at Monash University have developed the world’s first spaser (surface plasmon amplification by stimulated emission of radiation) made out of carbon. The spaser is a nanolaser that emists a beam of light through the vibration of free electrons and is much smaller than regular lasers. Besides being much smaller, the spaser would also be made with carbon. “Other spasers designed to date are made of gold or silver nanoparticles and semiconductor quantum dots while our device would be composed of a graphene resonator and a carbon nanotube gain element,” PhD student and lead researcher Chanaka Rupasinghe said. “The use of carbon means our spaser would be more robust and flexible, would operate at high temperatures, and be eco-friendly.

Even better than it being more eco-friendly is that the miniature technology would be so thin that it could eventually be printed onto clothing rather than contained in a hand held device. The strong and lightweight graphene and carbon materials would allow for a wide range of applications, especially in the field of wearable technology. Rupasinghe explains, “Because of these properties, there is the possibility that in the future an extremely thin mobile phone could be printed on clothing.” Soon you won’t have to go searching for your phone, because it will be right there with you on your clothes.
