Key points from article :
Soft, elastic, high-density stretchable electrode grid developed.
Suitable for long-term, stable neural recording and treatment of neurological disorders.
Avoids the usual damage to neurons from rigid metallic components.
Consists of gold coated titanium dioxide nanowires embedded into silicone rubber.
Uses very little material so can use gold without becoming too costly.
