Skin-breathable and stretchable strain sensors have received considerable interest from many research groups due to their applications in healthcare, and motion detection. In this study, a stretchable thin film with pockmarks was fabricated by bar coating with a mixture of carbon nanotubes (CNTs), non-solvent, and polymer solution. We could make the film in a short time with the simple process. The film, which has tens of micrometers scale of film thickness could improve gas permeability and skin attachability. pockmarks of the film could enhance stretchability by dispersing deformation stress on the film. Furthermore, CNTs in the elastic matrix reduced electric resistance and opened up possibilities for strain sensors. |
