A high-density, stretchable, 32-electrode grid for neural recording and neurological disorder treatment

A potential Neuralink device? (see SXSW video)
March 12, 2018

Photo of a new soft, elastic, high-density 32-electrode grid for long-term, stable neural recording and treatment of neurological disorders. It’s based on a novel elastic material that's biocompatible and retains high electrical conductivity, even when stretched to double its original length. The 32 electrodes shown here are each 50 micrometers wide and located at a distance of 200 micrometers from each other. The fabrication procedure allows 32 electrodes to be placed onto a very small surface. The electrode grid is 3.2 millimeters wide and 80 micrometers thick. (credit: Thor Balkhed)
