Problem
Wearable and flexible electronic devices require power sources that can bend, endure washing, and operate reliably across extreme temperature ranges, while advanced magnet systems need high‑temperature superconducting (HTS) materials that can be manufactured into practical wire and tape forms. Existing rigid batteries and limited‑availability HTS components restrict product design, durability, and performance in sectors such as medical wearables, defense, and energy infrastructure.
Solution
Flexenergy LLC addresses these gaps by developing two complementary material platforms. The Nava Flex Battery line delivers thin, flexible, and washable lithium‑based cells engineered to conform to body movements and maintain stable output from –40 °C to +80 °C, enabling seamless integration into next‑generation wearable technology. In parallel, the Nava Flex Supercon portfolio provides domestically produced high‑temperature superconductor materials, including multifilamentary round wires and coated conductors, designed for high critical current density and compatibility with next‑generation magnet systems. Both product families are manufactured with scalable processes and supplied to OEMs, allowing designers to incorporate reliable power and superconducting performance without extensive re‑engineering.
Target Audience
Primary customers include wearable technology manufacturers, medical device firms, defense and aerospace contractors, and developers of high‑performance magnet and power‑grid systems that require flexible power sources or HTS conductors.
