Abstract
The present invention relates to a fiber composite for a strain sensor and a method for producing the same. The composite includes a stretchable fiber; a conductive elastic polymer layer coated on the stretchable fiber; polymer beads disposed on the stretchable fiber or on the elastic polymer layer; and a conductive elastic polymer layer covering the polymer beads. The fiber composite is durable and stable. Therefore, a strain sensor produced using the fiber composite exhibits excellent durability, recoverability, repeatability and sensitivity, and a fast sensing speed.
Claims9
A fiber composite for a strain sensor, the fiber composite comprising:
- a stretchable fiber;
- a conductive elastic polymer layer coated on the stretchable fiber;
- and
- polymer beads disposed on the conductive elastic polymer layer,
- wherein the polymer beads are also coated with the conductive elastic polymer layer to allow the polymer beads not to be separated from the conductive elastic polymer layer in response to a strain being applied to the fiber composite, and
- wherein the polymer beads are polydimethylsiloxane (PDMS) present in an amount of 5-10% by weight.
