Une "surface" imprimée en 3D (encre spéciale) pour que des neurone puissent être "écoutés" avec le moins de dommages possibles.
Je cite:
MIT engineers are working on developing soft, flexible neural implants that can gently conform to the brain’s contours and monitor activity over longer periods, without aggravating surrounding tissue. Such flexible electronics could be softer alternatives to existing metal-based electrodes designed to monitor brain activity, and may also be useful in brain implants that stimulate neural regions to ease symptoms of epilepsy, Parkinson’s disease, and severe depression.
On est encore loin de "Johnny Mnemonic" (film de 1995) mais ça avance ;)
Un peu de Cyberpunk™ inside ;)
