Abstract
Provided are sensors comprising one or both of MXene-coated fibers and MXene-coated yarns.
Claims14
A pressure sensor, comprising:
- an assembly comprising:
- a first fabric electrode;
- a second fabric electrode;
- and
- a dielectric material disposed between the first fabric electrode and the second fabric electrode,
- at least one of the first fabric electrode and the second fabric electrode comprising (a) a substrate fiber, the substrate fiber defining an outer surface coated with a first plurality of MXene particulates, (b) a yarn comprising a plurality of coating fibers, each coating fiber comprising a substrate fiber defining an outer surface coated with a first plurality of MXene particulates, (c) a yarn comprising a plurality of coating fibers, each coating fiber comprising a substrate fiber defining an outer surface coated with a first plurality of MXene particulates and the yarn defining an outer surface coated with a second plurality of MXene particulates, or (d) a yarn comprising a plurality of fibers, the yarn defining an outer surface coated with a second plurality of MXene particulates,
- and wherein the first fabric electrode comprises a first yarn comprising a plurality of coating fibers, each coating fiber comprising a substrate fiber defining an outer surface coated with a first plurality of MXene particulates having a first average cross-sectional dimension, the first yarn further comprising a second plurality of MXene particulates having a second average cross-sectional dimension and being infiltrated between coating fibers, the first average cross-sectional dimension being larger than the second average cross-sectional dimension.
