Patent ID: 7554111

Claim:
A bistable electrical device that is convertible between a low resistance state and a high resistance state, said device comprising: a bistable polymer body which is electrically convertible between said low resistance state and said high resistance state, said bistable polymer body comprising a first surface which defines a first electrode location and a second surface which defines a second electrode location, said bistable polymer body comprising an electrically insulating polymer material in which doped nanofibers are dispersed, said doped nanofibers comprising electrically conductive nanoparticles doped at least one of on or in nanofibers wherein said bistable polymer body is converted between said low resistance state and said high resistance state by application of an electrical voltage to said bistable polymer body; a first electrode attached to said bistable polymer body at said first electrode location; and a second electrode attached to said bistable polymer body at said second electrode location, wherein each of said nanofibers has a width and a length, said length being longer than said width, and wherein said width is at least 3 nm and less than 120 nm.
