Stanford engineers design ant-sized radio to control ‘Internet of Things’


[MUSIC]>>Stanford University.>>What we’ve done here is figured out how
to design a radio in which everything, all the functionality of radio is
integrated on a single silicon chip, which is a few millimeters on the side. That includes the antennae devices,
the synchronization, computation, communication, everything
on a single chip. And we’ve done power harvesting,
where the device actually recovers and harvests power from the incoming signal,
computes, and communicates back using very narrow
pulses at 60 Gigahertz frequency. Now the advantage of moving
to this architecture is that we can have
the scalability that we want. We can scale the number of radios to
thousands in a very dense environment. We can also have,
because there is no battery connected, there’s essentially no life time
associated with these devices. As long as the signal is coming in they
can recover the power, communicate and communicate back. And the cost is extremely low because
we’re talking about a few millimetres of silicone chip. Which is a few cents to
manufacture on the large scale. So, we’ve basically rethought designing
radio technology from grounds up, and, we’ve kind of designed
the technology scale in numbers and size. This is the next wave of wireless devices. And that’s what people call
internet of things, or some people call internet of everything. And this is where internet moves from your
mobile devices, from your tablets and, and your cell phones into everyday objects,
and these objects will start making decisions based on minimal supervision
because they have wireless connectivity, they have some kind of sensing,
they have computational power. You’ll have these on your coffeemaker,
you’ll have it on your fridge. And, and decisions, and, and, and
communication between these objects will enable a whole new wave
of functionality and a whole new wave of how we interact
with the objects around us.>>For more,
