Fabrication process for CSNF-based electrodes for peripheral nerve stimulation. a Schematic of the fabrication process of CSNF paper electrodes. b, c Images of laser-patterned PI masks. PI masks are directly patterned by a laser ablation process (b), and removed gently after filtration to fabricate CNT micropatterns (c). d, e AFM images of the CSNF (d), and CNT network on CSNF (e). f An image of a CSNF paper electrode for in vivo experiments. g, h Laser-scanned 3D images of the surface topology of the electrode that is used for in vivo experiments. i An example of a patterned paper electrode without passivation. Scale bars: (b) 5 mm, (f) 2.5 mm (g, h) 100 µm (i) 1 cm
