Abstract: Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including colorant(s), an exposed first outer surface, an exposed second outer surface, and a recess in the first outer surface not reaching the second outer surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes colorant(s). The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

Abstract: Disclosed herein are wireless wearables and related systems and methods. The wireless wearables are devices worn by a user (and/or attached to clothing and/or accouterments of a user) and are configured to receive and send data based on one or more wireless communication technologies, such as for authentication for a variety of purposes. The wearables may include, by non-limiting examples: rings (finger rings and/or toe rings), necklaces, earrings, piercings, clasps, watch bands, charms, cuff links, pins or clip elements attachable to clothing, pins or clip elements attachable to a bill of a hat, and clip or magnetic elements attachable to glasses (eyeglasses, sunglasses, virtual reality glasses, augmented reality glasses, and so forth).

Abstract: Rings disclosed herein include a toroid formed of an expandable polymer, the expandable polymer having an elastic modulus of no greater than 5 gigapascals (GPa), the expandable polymer forming at least 80 weight percent of the toroid, the toroid sized to fit snugly over a digit of a user. In implementations a plurality of precious material particles are disposed within the expandable polymer, wherein the precious material particles include one or more of gold particles, non-ionic silver particles, copper particles, platinum particles, and crushed pearl particles. In implementations a plurality of grooves are formed on an inner surface of the ring and extend from proximate a top of the ring to proximate a bottom of the ring. In implementations no portion of the ring has an elastic modulus greater than 5 GPa.

Abstract: User-wearable rings are disclosed that are expandable, antimicrobial, and/or breathable. Each ring is shaped into a toroid formed at least partly of an expandable polymer having an elastic modulus no greater than 5 gigapascals (GPa). The toroid is sized to fit snugly over a digit of a user and is configured to expand as needed. Some ring implementations include antimicrobial elements disposed within the expandable polymer. In some implementations the antimicrobial elements include ionic silver. Some ring implementations include precious materials, such as precious metals or crushed pearl, interspersed within the expandable polymer. Some ring implementations include one or more colorants having a color matching the color of one or more precious materials interspersed in the ring. Some ring implementations include grooves formed on an inner surface of the ring and allowing moisture, dirt, grime, and the like to exit from between the digit of the user and the ring.
