Resistance-switching device having conductive fiber, fabric type resistance-switching device array having the same, memory and sensor having the device or the array

A resistance-switching device comprising:

• a first wiring including an aluminum oxide surface layer;
• and
• a second wiring including a carbon-containing surface layer in contact with the aluminum oxide surface layer,
• wherein:
• electrochemical reaction products according to a reaction of aluminum oxide and carbon are generated or destroyed at a contact interface between the aluminum oxide surface layer and the carbon-containing surface layer according to a voltage or a current applied to the first wiring and the second wiring;
• low resistance and high resistance are provided between the first wiring and the second wiring by the generation or destruction of the electrochemical reaction products;
• and
• the electrochemical reaction products are aluminum oxycarbide.

A resistance-switching device comprising:

• a first conductive fiber including an aluminum oxide surface layer and an aluminum layer below the aluminum oxide surface layer, wherein the aluminum oxide surface layer is a native oxide film of the aluminum layer;
• and
• a second conductive fiber including a carbon-containing surface layer in contact with the aluminum oxide surface layer,
• wherein the first conductive fiber and the second conductive fiber are woven or knitted, or have a fabric type which is combined on another insulating support by being stitched thereto.
