2. Improved Brain Stimulation Device Powered by Metamaterials

University of Michigan engineers recently used a metamaterial to construct a magnetic array able to provide finer and deeper brain stimulation than previously possible. 

The prototype, recently announced by the university, could potentially lead to transcranial magnetic stimulation coils that are more effective at treating depression or exploring the workings of the human brain. 

It also represents another example of the promise metamaterials hold when it comes to medical device design. A metamaterial is an artificial material engineered with precise shape, geometry, orientation and arrangement--with structures often at an exact subwavelength size, smaller than the wavelength of whatever form of energy is affected. 

Metamaterials have shown promise in other medical device applications, such as making untrasound imaging high def.
