Abstract: A health monitoring device is provided, and may be used in population health monitoring and disease tracing, as well as for individual subject health purposes. The health monitoring device comprises a triboelectric nanogenerator (TENG) for generating and storing electrical energy from mechanical activity of a user. The device provides a continuous and uninterrupted stream of physiological data received at a surface of the device in contact with a surface of the user. The triboelectric nanogenerator is a paper-based device comprising a paper-based material layer and a polydimethylsiloxane/polytetrafluoroethylene (PDMS/PTFE) material layer, each on a copper film. The device has enhanced sensitivity to motion, providing an improved device capable of converting small amounts of movement into electrical energy, and of recording and transmitting data of small physiological changes of a user to a receiver. The device is lithium free, and eliminates the necessity of recharging.

Abstract: A power and/or electricity generating source and/or component that is TENG-based, and that may be configured as an assembly and/or component for powering one or more electronic devices, is disclosed, A case, carrier or other carrying container, for example a case for a cell phone, ipad, electronic tablet, personal computer, or any similar device, that provides an electricity source to power the cell phone, ipad, electronic tablet, is disclosed. The energy generating carriers and/or containers and configurations thereof, also provide an electricity energy storage source. This electronic energy storage source may be incorporated within an electronic device itself, or may be incorporated within the case and/or covering. Upon walking or touching a surface of an electronic device, the power generating source will harness mechanical energy, and provide for the generation of electricity with the one or more TENG components (TESTEC) that comprise the energy generating unit. Metal particles (silver, copper, etc.

Abstract: A method for forming a metallic nanoparticle and semiconductor coated fiber material is provided. The method can include the steps of coating at least one surface of a material, for example a textile material, with a semiconducting layer, and growing metallic nanoparticles on the semiconducting layer. The steps for coating the surface of the material with a semiconducting layer can include forming a titanium dioxide film on the surface of the textile material. The steps for forming metallic nanoparticles on a semiconducting layer can include immersing the coated textile layer in a metallic nanoparticle precursor solution, drying the coated textile layer and exposing the textile layer to UV radiation. The metallic nanoparticles can include gold and/or silver nanoparticles. Also disclosed are materials having a least one treated surface coated with metallic nanoparticles. The treated surface may comprise the surface of a textile material treated according to the methods provided herein.

Abstract: A method for forming superior and stable metallic nanoparticle and semiconductor coated fiber materials is provided. The method can include the steps of coating at least one surface of a material, for example a textile material, with a semiconducting layer, and growing metallic nanoparticles directly on the semiconducting layer. The steps for coating the surface of the material with a semiconducting layer can include forming a titanium dioxide film on the surface of the textile material, immersing the coated textile layer in a metallic nanoparticle precursor solution, drying the coated textile layer and exposing the textile layer to UV radiation. The metallic nanoparticles can include gold and/or silver nanoparticles. Also disclosed are materials resistant to microbes, including bacteria and viruses. These materials comprise at least one treated surface coated with metallic nanoparticles. The treated surface may comprise the surface of a textile material, such as a cotton fiber surface.
