In a first-of-its-kind attempt, U.S. and Chinese scientists have developed a new method to inject microelectronic devices such as wires and transistors directly into the brain (or other body parts), that could lead to sophisticated new ways to treat conditions ranging from neurodegenerative disorders to paralysis.

Researchers have developed stretchy, bendy electronics that are so thin that they can be rolled up and jammed into a small needle with a 0.1-millimeter diameter. These electronics are then injected into living tissue using syringes. The research involved injecting the electronics into the brains of live mice. Within an hour of being injected, the electronics unfurled and began monitoring biological activity.

Previous research revealed that electronics like these can be surgically implanted, but so far, it hasn’t been possible to precisely control their delivery to non-invasive target…
