Researchers at the Georgia Institute of Technology and Emory University have developed a wireless sensor small enough to be implanted in the blood vessels of the human brain.

The stretchable sensor operates without batteries, and is designed to be wrapped around stents or diverters implanted to control blood flow in vessels affected by brain aneurysms.

The researchers used a three-dimensional-printing/additive manufacturing technique to create the sensors. The technique allows production of very small electronic features in a single step.

The sensor includes a coil that can pick up electromagnetic energy transmitted from another coil located outside the body.
