Wear Your Smartphone

Updated: May 17, 2014 4:26 pm

Wearable technology is going to be the next level in technology that can print your device on your t-shirts. The idea isn’t crazy but is a new research done by the team of Monash University’s Department of Electrical and Computer Systems Engineering (ECSE). This technology is named as ‘spanser’—a nanolaser technology that can develop really small and flexible, yet efficient mobile phones that can be printed—which will take the computing technology to the next level.

Spaser (Surface Plasmon Amplification by Stimulated Emission of Radiation) are nanoscale lasers that emit a beam of light through the vibration of free electrons, as opposed to the relatively space-consuming beam of a traditional laser. This new spaser laser is entirely made of carbon, which gives it plus point over the other spaser lasers. Traditionally, all the spasers are created using gold or silver nanoparticles and semiconductor quantum dots. But the ECSE team has developed its nano laser using a graphene resonator and a carbon nanotube gain element. The team ensures that the use of carbon in the laser would be more robust and flexible enough to operate at high temperatures and side by side will be eco-friendly. Due to these properties there is possibility that in the future an extremely thin mobile phone could be printed on clothing.

The team believes that its spaser technology would soon replace transistor-based devices such as microprocessors, memory etc and would remove the current miniaturising and bandwidth restrictions. Spaser would be built using graphene and carbon nanotubes, which are over a hundred times harder than steel and have superior heat and electricity conduction capabilities. Owing to their outstanding mechanical, electrical and optical properties graphene and carbon nanotubes can be used in applications where there is a need of strong, lightweight conducting, and thermally stable materials.

Not limiting the applications of their research to just the techno-gadget world, the team went on to share that it has really good use in medical field too. Some researchers have proved that there’s a way to guide nanoparticles to destroy cancer cells, and that too without harming the healthy cells in the body.
