US Patent 12133465 Multilayer functional fiber and method of making

A method is provided for making a multilayer functional fiber, where the method includes: providing a scaffold fiber; disposing a first electrode layer enclosing the scaffold fiber; disposing a functional layer enclosing the first electrode layer, the functional layer having a functional characteristic varying as a function of longitudinal position along the functional layer; disposing a second electrode layer enclosing the functional layer; and disposing a cladding layer enclosing the second electrode layer. In another aspect, a multilayer functional fiber is provided produced by, for instance, the above-noted method.
