Metamaterials could make it possible to transmit wireless power while avoiding the complications associated with microwaves or lasers, engineers at Duke University say.
The material would be situated between a power source and a device to be charged, and it would serve as a sort of a bridge so that there appeared to be no space between the transmitter and the recipient.
Wireless TV just got a whole new meaning. Sony has just announced a new short-range, intra-gadget technology that clocks a 11Gbps transfer speed. The tech, known as millimeter-wave, allows electronics innards to communicate wirelessly with one another, which could allow for slimmer designs and fewer wires--that means fewer connections to sever, and potentially more reliable gadgets.
