Abstract
A knitted fabric structure that includes a piezoelectric yarn having a piezoelectric material that produces a surface potential by input of an external force from an outside of the piezoelectric yarn; and an elastic yarn having stretchability knitted together with the piezoelectric yarn, wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure.
Claims17
A knitted fabric structure comprising:
- a piezoelectric yarn comprising polylactic acid as a piezoelectric material and that produces a surface potential by input of an external force from an outside of the piezoelectric yarn, the piezoelectric yarn having a first loop;
- wherein the first loop does not include an elastic yarn;
- and
- an elastic yarn having an elongation recovery rate of 40% or more, the elastic yarn having a second loop,
- wherein the second loop of the elastic yarn is hooked to the first loop of the piezoelectric yarn,
- wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure, and
- wherein the elastic yarn has a mixing ratio of 35% or more based on the whole of the knitted fabric structure.
