Researchers at the North Carolina State University used the breath figure method to create a stretchable polymer film featuring an even distribution of holes. The film is coated by dipping it in a solution that contains silver nanowires and heat-press the material to seal the nanowires in place. The resulting a few micrometers thick film showed an excellent combination of electric conductivity, optical transmittance and water-vapor permeability and stability in the presence of sweat and after long-term wear. They demonstrated the material’s potential for use in wearable electronics and electrophysiologic sensors…read more. TECHNICAL ARTICLE
