A method for fabricating polymeric sheets containing microwires includes encapsulating at least a portion of individual lengths of a plurality of microwires in a non-conductive polymeric sheet while the microwires are attached to the substrate. The microwires are then detached from the substrate without removing the microwires from the polymeric sheet. The detaching step forms a separated polymeric sheet containing the detached microwires. Individual detached microwires of the plurality are approximately perpendicular to the separated polymeric sheet. A microwire array device includes a non-conductive polymeric sheet and a plurality of microwires. Individual microwires of the plurality have an independent length at least partially encapsulated by the polymeric sheet, are approximately perpendicular to the polymeric sheet, and contain magnetic ferrite.

Isolation tortuous path seal enclosure
11706907 · 2023-07-18 · ·

A modular system of plastic walls having embedded and coextensive electrically conductive components configured to electrically connect with each other when the walls are mated. The walls have joining edges that form joint seams with other walls when joined together to create an enclosure. When enough walls are used to surround a storage space, a Faraday cage is created. The walls additionally have portions of tortuous paths at each joining edge that mate with a complementary portion of a tortuous path of another wall when the walls are joined together. A torturous path seal is thereby created at each joint seam. The plastic walls can be configured in a multiplicity of combinations to create various enclosures necessary for RFID-enabled storage and tracking of medical articles. Containers, enclosures, cabinets, and drawers of differing heights and sizes can be made and they may be stacked or otherwise assembled.

Programmable wire filaments and devices
11706908 · 2023-07-18 · ·

A switchable wire includes filaments, each of which includes a heat-activated material layer that may be indirectly heated to change its state between different states having different electrical conductivity. In an example embodiment the indirect heating may be electrically resistance heating by passing electrical current through an electrically-resistive core of the filament. The heat passing through an electrically-insulative coating around the core, and into a heat-activated material layer around the electrically-insulative coating. The heat-activated material may be a chalcogenide material that is shiftable between a crystalline electrically-conducting state and an amorphous electrically-insulating state. The state of the material may be controlled by controlling the heating profile through controlling heating in the core. Many such filaments may be twisted together to form a switchable wire. Such wires may be used in any of a variety of devices where switchable electrical conductivity is desired.

Nanofiber fabric
11549205 · 2023-01-10 · ·

A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.
