Lede: A new technique might soon allow you to stream High Definition video from a camera so small it could be attached to your glasses.

Randy Atkins: The tiny camera would wirelessly send its images to your smart phone. Joshua Smith, an engineer at the University of Washington, says it’s engineered to reflect radio waves, beamed from a plugged-in device, to send the pictures.

Joshua Smith: Instead of having a battery, if we can power these devices using radio waves not only does it enable wearable devices, but you can build sensors into all kinds of places where it just wouldn't be feasible to service batteries.

Randy Atkins: This technology could be used to advance smart city and home applications. It might even be used in medicine.

Joshua Smith: If you could implant cameras inside the body in various places, there's a lot of, a physiological information you could probably get from that.

Randy Atkins: And Smith says as energy efficiency of microelectronics continues to improve, the potential uses for this camera technology will only grow. With the National Academy of Engineering, Randy Atkins, WTOP News.
