Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

Scientists have achieved a milestone in creating a building block for the future of wireless devices. Researchers have announced the first integrated circuit fabricated from wafer-size graphene, and ...

A system that turns brain waves into FM radio signals and decodes them as sound is the first totally wireless brain-computer interface. For now, 26-year-old Erik Ramsey, left almost entirely paralyzed ...
