High-Density Stretchable Electrode Grids for Chronic Neural Recording.

Abstract in brief

• This research introduces a soft, stretchable electrode grid made from high-performance composite materials, such as gold-coated titanium dioxide nanowires embedded in silicone, designed for long-term neural recording without losing signal quality.
• The flexible and durable nature of this electrode allows it to reliably pick up neural signals from the surface of a rat’s brain over three months, even as the animal moves freely, addressing previous challenges related to mechanical mismatch.
• The design's flexibility also reduces the invasiveness of brain surgery by enabling smaller craniotomies, and the technology has potential applications across various biomedical fields for more stable and detailed neural interfaces.]
