Scientists say they have developed the first bioelectronic medicine — an implantable, biodegradable wireless device that speeds nerve regeneration and improves the healing of a damaged nerve. Researchers at the Washington University in the U.S. developed a device that delivers regular pulses of electricity to damaged peripheral nerves in rats after a surgical repair process, accelerating the regrowth of nerves in their legs. About the size of a small coin, the wireless device operates for two weeks before getting absorbing into the body, according to the study published in the journal Nature Medicine .
