writes with this excerpt from news out of Carleton University: “Atif
Shamim, an electronics PhD student at Carleton University, has built a
prototype that extends the battery life of portable gadgets such as the
iPhone and BlackBerry, by getting rid of all the wires used to connect
the electronic circuits with the antenna. … The invention involves a
packaging technique to connect the antenna with the circuits via a
wireless connection between a micro-antenna embedded within the
circuits on the chip. ‘This has not been tried before — that the
circuits are connected to the antenna wirelessly. They’ve been
connected through wires and a bunch of other components. That’s where
the power gets lost,’ Mr. Shamim said.” The story’s headline claims the
breakthrough can extend battery life by up to 12 times, but that seems
to be a misinterpretation of Shamim’s claim that his method reduces the
power required to operate the antenna by a factor of about 12; 3.3 mW
down from 38 mW. The research paper (PDF) is available at the Microwave
Journal. imamac adds, “Unlike many of the breakthroughs we read about
here and elsewhere, this seems like it has a very high probability of
market acceptance and actual implementation.”
