Strain Sensors: A Highly Sensitive and Reliable Strain Sensor Using a Hierarchical 3D and Ordered Network of Carbon Nanotubes (Small 25/2015)

The film fabricated by H. Lee and co-workers on page 2990 has ordered, interconnected single-walled cabron nanotubes (SWCNTs) as a result of a simple transfer method using a hierarchical SWCNT structure grown on a Si pillar substrate. This is the new approach for the directional 3D alignment of SWCNTs in a polymer matrix. The Si pillar structure can be used as a sensor template for supporting the ordered 3D network arrangement of SWCNTs. This film should be applicable to many fields involving mechanically stable and reliable strain sensors.
