First magnetoelectric material solves nerve signal problems

A study finds a material that is 120 times faster than similar ones, demonstrating its precision in remotely stimulating neurons and repairing severed sciatic nerves in rats.

The researchers demonstrated the material's ability to remotely stimulate neurons and repair a severed sciatic nerve in rats with precision. “With that question in mind, we thought that magnetoelectric materials were ideal candidates for use in neurostimulation. They respond to magnetic fields, which easily penetrate into the body, and convert them into electric fields ⎯ a language our nervous system already uses to relay information.”

The researchers applied platinum, hafnium oxide, and zinc oxide layers on top of the first magnetoelectric film to address challenges in compatible fabrication techniques.Bhave stated: “This reduced the size of the entire device so that in the future it could be injectable,”
