A wing-inspired electrode array balances softness and handling

A September Nature Communications paper introduces a freestanding, submicron electrocorticography array inspired by a dragonfly wing's vein-and-membrane structure. The aim is to combine close contact with the brain surface and enough structural support for handling.

Making an array thinner can improve conformability, but it can also make placement harder. A design must survive the surgical workflow as well as record useful activity afterward.

This is an interface-engineering result. Its relevance to future BCIs lies in that mechanical trade-off; it does not by itself establish the communication speed, long-term reliability or clinical usefulness of a complete implanted system.
