Woven thermoelectric ribbon

A woven structure includes thermoelectric ribbons interwoven with thread. Each thermoelectric ribbon includes a folded matrix of thermoelectric elements, the matrix having an insulating substrate that supports plural rows of thermoelectric elements, a plurality of conductive elements, and two terminals. The conductive elements form a series connection of the thermoelectric elements between the two terminals. A set of first conductive elements have a first temperature and a set of second conductive contacts have a second temperature lower than the first temperature when a first current flows in a first direction between the first matrix terminal and the second matrix terminal. The folded matrix is configured to form spaced-apart alternating stacks of the first conductive contacts and second conductive contacts. Each length of the yard or thread is interwoven such that it passes alternately under stacks of first conductive contacts and over stacks of second conductive contacts.

Stable conductive myocardial patch with negative Poisson's ratio structure and preparation method thereof

A stable conductive myocardial patch with a negative Poisson's ratio structure is provided. The preparation method includes preparing a myocardial patch substrate with concave polygons as the structural units by weaving or knitting, and then a conductive coating is coated on the surface of the substrate. Alternatively, the yarns can be processed into conductive coated yarns first, and then used as the raw material to weave or knit a stable conductive myocardial patch with a negative Poisson's ratio structure. The prepared myocardial patch has a relative resistance change of less than 5% at 50% tensile strain. When the strain of the structural units is within 50%, the fabric exhibits a negative Poisson's ratio structure, which expands in the perpendicular direction of the tensile load. The fabric exhibits a negative Poisson's ratio effect and anisotropy of Young's modulus, which matches the mechanical behavior of natural myocardium.

20220250931 · 2022-08-11 ·

An innovative high-energy oxidative method using metallic copper and chlorine liquid to produce a superior copper chloride II element using electromagnetic induction and magnetic forces. This invention involves copper undergoing oxidation while in its highest energy state according to basic principles of electromotive forces described in Faraday's law. The copper attaches to a magnetic receptacle and held in place by a copper lid cover. Research studies demonstrate that metallic copper is not magnetic; however, when a magnetic field approaches copper, the electrons and subatomic particles forms a higher resistance against the magnets—Generating a force field response towards the approaching magnets. The oxidation of copper in its highest energy state provides additional improvements and benefits in copper's antimicrobial and antiviral properties. This new method for oxidizing copper chloride in its highest subatomic energy state provides vast improvements and coverage in the fight against microorganisms and the invisible pathogens abroad.
