Why graphene speakers could become the audio industry’s new gold standard

We’ve heard a lot about graphene being a “wonder material” that could be used for smartphone casings and antennas, but now it seems that some engineers have found a way to incorporate it into audio speakers and headphones as well. Technology Review reports that University of California Berkeley researchers Qin Zhou and Alex Zettl have found that graphene is the perfect material for constructing speaker diaphragms, which typically work best when made from a thin material that reduces the need to conduct expensive and energy-consuming “damping engineering.” More →

How graphene antennas could pave the way for terabit wireless data speeds

While gigabit Wi-Fi seems to be all the rage these days, some researchers at Georgia Tech are working on new technology that makes even the fastest wireless networks look like dial-up in comparison. Technology Review reports that Georgia Tech’s broadband wireless networking laboratory has been experimenting with making antennas out of graphene,  a two-dimensional “super-material” that measures just one atom thick and has been described by Nokia (NOK) as the “strongest material ever tested, having a breaking strength 300 times greater than steel.” But while a lot of attention has been paid to graphene’s potential for manufacturing incredibly thin and light gadget casings, the researchers at Georgia Tech are using it to create an antenna capable of transmitting data at a rate of a terabit per second.
