Abstract

A 3D network of single‐walled carbon nanotubes embedded in poly­(dimethylsiloxane) is presented as a promising route to the fabrication of a flexible film with ordered and interconnected single‐walled carbon nanotubes. This is possible using a simple transfer method of as‐grown hierarchical single‐walled carbon nanotubes on a Si pillar substrate. This film is used as a highly sensitive strain gauge sensor. This type of network embedded in a polymer film should be applicable to many fields involving mechanically stable and reliable strain sensors.
