Abstract

A method of manufacturing a fiber-based electric apparatus includes providing an elongate, flexible fiber core and layering an electric device on the fiber core.

Claims (25)

1. A method of manufacturing an electric apparatus comprising:

providing a plurality of fiber-based electric apparatuses, each including an elongate flexible fiber core and at least one electric device layered thereon, at least one of the plurality of fiber-based electric apparatuses including a plurality of first films and second films, the first and second films alternatingly arranged along the axis of the respective fiber core, the first films abutting corresponding ones of the second films such that a plurality of junctions are defined between corresponding pairs of the first and second films; and

operably securing the plurality of fiber-based electric apparatuses together into a mat that defines a first side and a second side such that a location of the plurality of junctions alternates in succession between the first side and the second side along the axis of the respective fiber core.

2. The method of claim 1 , wherein operably securing includes weaving the plurality of fiber-based electric apparatuses together into the mat.

3. The method of claim 1 , further comprising at least one of converting electricity to light with the electric apparatus, converting light to electricity with the electric apparatus, converting heat to electricity with the electric apparatus, and converting electricity to heat with the electric apparatus.

4. The method of claim 3 , further comprising at least two of operating the electric apparatus as a photovoltaic device, a thermoelectric device, and a light emitting device.

5. The method of claim 1 , wherein operably securing includes placing at least one of the fiber-based electric apparatuses in electric communication with another of the fiber-based electric apparatuses.

6. The method of claim 1 , further comprising interweaving a plurality of secondary fibers with the plurality of fiber-based electric apparatuses such that the secondary fibers each extend transverse to the axis of the respective fiber core and such that the secondary fibers each overlay a respective one of the plurality of junctions.

7. The method of claim 1 , wherein providing a plurality of fiber-based electric apparatuses includes providing the flexible fiber core and layering the at least one electric device on the fiber core.

8. The method of claim 7 , further comprising unspooling the elongate, flexible fiber core and spooling the elongate-flexible fiber core to advance the fiber core during layering of the electric device on the fiber core.

9. The method of claim 7 , further comprising rotating the elongate, flexible fiber core about an axis of the elongate, flexible fiber core while layering the electric device on the fiber core.

10. The method of claim 7 , further comprising layering the at least one electric device via vacuum thermal evaporation.

11. A method of manufacturing an electric apparatus comprising:

providing a plurality of fiber-based electric apparatuses, each including an elongate, flexible fiber core and at least one electric device layered thereon, the plurality of fiber-based electric apparatuses including a first fiber-based electric apparatus and a second fiber-based electric apparatus, the first fiber-based electric apparatus including only one of a p-type material and an n-type material, the second fiber-based electric apparatus including only the other of the p-type material and the n-type material;

operably securing the plurality of fiber-based electric apparatuses together; and

electrically connecting the first and second fiber-based electric apparatuses together in parallel with at least one conductive member.

12. The method of claim 11 , wherein operably securing the plurality of fiber-based electric apparatuses together includes operably securing the plurality of fiber-based electric apparatuses together into a mat that defines a first side and a second side, and wherein electrically connecting the first and second fiber-based electric apparatuses together includes operatively connecting pairs of the first and second fiber-based electric apparatuses with a first conductive member adjacent the first side of the mat, and wherein electrically connecting the first and second fiber-based electric apparatuses together includes operatively connecting pairs of the first and second fiber-based electric apparatuses with a second conductive member adjacent the second side of the mat.

13. The method of claim 11 , further comprising positioning an insulating fiber between a pair of the first and second fiber-based electric apparatuses.

14. The method of claim 11 , wherein operably securing the plurality of fiber-based electric apparatuses together includes weaving the plurality of fiber-based electric apparatuses together.

15. The method of claim 11 , further comprising at least one of converting electricity to light with the electric apparatus, converting light to electricity with the electric apparatus, converting heat to electricity with the electric apparatus, and converting electricity to heat with the electric apparatus.

16. The method of claim 15 , further comprising at least two of operating the electric apparatus as a photovoltaic device, a thermoelectric device, and a light emitting device.

17. The method of claim 11 , wherein providing a plurality of fiber-based electric apparatuses includes providing the flexible fiber core and layering the at least one electric device on the fiber core.

18. The method of claim 17 , further comprising unspooling the elongate, flexible fiber core and spooling the elongate-flexible fiber core to advance the fiber core while layering the at least one electric device on the fiber core.

19. The method of claim 17 , further comprising rotating the elongate, flexible fiber core about an axis of the elongate, flexible fiber core while layering the at least one electric device on the fiber core.

20. The method of claim 17 , further comprising layering the at least one electric device via vacuum thermal evaporation.
