Chinese scientists have developed a nano-sized electric generator that can disappear without a trace inside the human body over time, a breakthrough they claim will bring biodegradable implants on microchips closer to reality.

The technology, reported on the latest issue of Science Advances journal, will have a wide range of applications as it can generate electric pulses to repair damaged neurons and power “brain chip” implants for soldiers in the future, pundits said.

At present, most implants must be surgically removed at the end of their lifespan. To address this issue, a number of small electric devices made from biodegradable materials that can absorbed by the human body after use have been developed around the world.
