Abstract: Textile-based electrodes include a fabric portion having stretch-recovery non-conductive yarns and an electrically conductive region having stretch-recovery electrically conductive yarn filaments. The electrodes can further include float yarns and can be configured in a textured or ribbed construction. When incorporated into a garment, the electrodes can be used to monitor biophysical characteristics, such as the garment wearer's heart rate.

Abstract: Energy active composite yarns include at least one textile fiber member of either an elastic or inelastic material, and at least one functional substantially planar filament, which surrounds or covers the textile fiber member. The composite yarns can include an optional stress-bearing member, which also surrounds or covers the textile fiber member. The composite yarns may be multifunctional, meaning the functional substantially planar filament can exhibit combinations of electrical, optical, magnetic, mechanical, chemical, semiconductive, and/or thermal energy properties.

Abstract: A surface functional electro-textile fabric incorporates energy-active, electrically conductive or optically conductive fibers and nonconductive fibers in a woven or knitted textile fabric. The weave or knit pattern is selected so as to form floats of the electrically conductive fibers on at least one surface of the electro-textile fabric. The electro-textile fabric can be incorporated into an antenna structure that interacts with high frequency electromagnetic radiation, particularly in the frequency range of DC to 100 GHz.

Abstract: A system and method for monitoring blood pressure of a wearer has an inflatable arm cuff that is selectably inflatable to differing air pressures that incorporates a fabric having both a light transmission property and a light reflection property when the fabric is illuminated with light having wavelength(s) in the range from about 400 to about 2200 nanometers. A radiation source and a detector are attached to the fabric in relative positions such that the reception of incident radiation by the detector is directly affected by a change in the amount of light transmitted through the fabric relative to the amount of light reflected by the fabric as the fabric stretches in response to motion in the wearer's body due to changes in the flow of blood through an artery disposed beneath the fabric occurring in consonance with variations in the air pressure within the inflatable cuff.
