Flexible Networks of Patterned Conducting Polymer Nanowires for Fully Polymeric Bioelectronics

Patterning of conducting polymers (CPs) into fully functioning devices remains a challenge for the creation polymeric bioelectronics. Presently, most successful method patterning CPs is preprocess blending with structural components and using either subtractive or additive processes to produce desired design. This work focuses on development characterization filter-based processing direct pattern transfer CP poly(3,4-ethylenedioxythiophene) (PEDOT) elastomeric substrates. Laser sintering surface filter membrane subsequent filtering PEDOT nanowires onto enable feature sizes approximately 400 μm be resolved without need any postprocessing. The resulting films patterned are found possess high conductivity as well improved wet electrochemical properties in comparison platinum. Using process developed this work, thin flexible arrays nanowire produced used an EMG device test muscle contractions.
