FLEXIBLE STRAIN SENSORS
First Claim
1. A flexible strain sensor comprising:
- a composite structure comprising a carbon nanotube film and a substrate combined with each other, the carbon nanotube film defining a desired deformation direction and comprising a plurality of first carbon nanotubes oriented along an orientation direction substantially perpendicular with the desired deformation direction, wherein the plurality of first carbon nanotubes are joined end to end with each other along their orientation direction;
a first electrode and a second electrode, the first electrode and the second electrode separately located, one at each of the two opposite ends of the carbon nanotube film and electrically coupled with the carbon nanotube film; and
a detector electrically connected with the first electrode and the second electrode.

Abstract
The present disclosure relates to a flexible strain sensor. The flexible strain sensor includes a composite structure, a first electrode, a second electrode and a detector. The composite structure includes a carbon nanotube film and a substrate combined with each other. The carbon nanotube film defines a desired deformation direction and includes a plurality of first carbon nanotubes oriented substantially perpendicular with the desired deformation direction. The plurality of first carbon nanotubes are joined end to end with each other along their orientation direction. The first electrode and the second electrode are separately located at two opposite ends of the carbon nanotube film and electrically coupled with the carbon nanotube film. The detector is electrically connected with the first electrode and the second electrode.
