Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes
Advanced Materials Technologies, EarlyView.This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...
