Microneedle Arrays
In article number 2112045, Shadi A. Dayeh and co‐workers have invented an advanced brain–computer interface with a flexible and moldable backing and penetrating microneedles, which are 10 times thinner than the human hair. The flexible backing allows the device to more evenly conform to the brain's complex curved surface and to more uniformly distribute the microneedles that pierce...
The Utah array powers cutting‐edge projects for restoration of neurological function, such as BrainGate, but the underlying electrode technology has itself advanced little in the last three decades. Here, advanced dual‐side lithographic microfabrication processes is exploited to demonstrate a 1024‐channel penetrating silicon microneedle array (SiMNA) that is scalable in its recording capabilities...
