Bioengineers at Rice University have developed a novel metamaterial that can generate a steady microvolt electrical current when its exposed to an alternating magnetic field. Implanting this material in select portions of the brain would permit clinicians to stimulate specific neural centers by exposing a patient to a focused magnetic field. The device requires no internal power source. So far, the researchers have used the material to wirelessly trigger nerve signals in the peripheral nerves of experimental animals. With refinement, the technique could come to the clinic…..Someday soon.
