Traditional Neural Electrodes Versus Mesh Electronics

Caption

A traditional neural electrode (top panel) provokes an immune response in the brain while a mesh electronic interface (bottom panel) does not. The size and rigidity of current electrodes provoke chronic inflammation, causing glial scarring between brain tissue and electrode and degrading the neural interface. Mesh electronics evade the immune response due to cellular and sub-cellular features and bending stiffness resembling the brain itself.
