Abstract: A method includes applying an electrical signal to a tissue and measuring an impedance of the tissue based on the applied electrical signal. The method further includes determining information indicative of a stage of wound healing based on the impedance and outputting information indicative of the stage of wound healing.

Abstract: A method and system for tissue impedance measurement are disclosed. In examples, the system comprises electrical contacts configured to be coupled to a first tissue and a first device configured to apply a first electrical signal to the first tissue via the electrical contacts. The system further comprises a second device configured to determine a first impedance phase angle of epithelial tissue of the first tissue site based on the first applied electrical signal, determine a baseline impedance phase angle of epithelial tissue corresponding to a second tissue, determine information indicative of epithelial tissue characteristics based on a ratio of the first impedance phase angle and the baseline impedance phase angle, and output information indicative of the epithelial tissue characteristics.

Abstract: Ultraviolet-C (UV-C) radiation shielding films including a substrate made of a fluoropolymer, a multilayer optical film disposed on a major surface of the substrate, and a heat-sealable encapsulant layer disposed on a major surface of the multilayer optical film opposite the substrate. The multilayer optical film is made of at least a multiplicity of alternating first and second optical layers collectively reflecting at an incident light angle of at least one of 0°, 30°, 45°, 60°, or 75°, at least 30 percent of incident ultraviolet light over at least a 30-nanometer wavelength reflection bandwidth in a wavelength range from at least 100 nanometers to 280 nanometers. The ultraviolet light shielding film may be applied to a major surface of a photovoltaic device, such as a component of a satellite or an unmanned aerial vehicle. Methods of making the UV-C radiation-protective films also are disclosed.

Abstract: A PTSM-coated expandable microsphere comprises a polymer shell enclosing an interior volume containing at least one blowing agent. The polymer shell has an outer surface with photothermal susceptor material disposed on at least a portion thereof. If heated to at least one temperature greater than 25° C., each of the expandable microspheres expands, but does not rupture, the polymer shell by a sufficient amount to at least double the interior volume. A markable comprises a substrate and a viewable layer secured thereto. The viewable layer comprises a binder material retaining the PTSM-coated expandable microspheres. A method of marking a markable article comprises imagewise exposing the PTSM-coated expandable microspheres of the markable article to at least sufficient electromagnetic radiation to cause the PTSM-coated expandable microspheres to expand thereby creating a predetermined image. A marked article preparable according to the method is also disclosed.
