Systems and methods of heating a fiber producing device

1. A microfiber and/or nanofiber producing system comprising:

a fiber producing device comprising a body comprising one or more openings and a coupling member, wherein the body is configured to receive a material to be produced into a fiber;

an inductive heater positioned proximate to the fiber producing device such that, during use, the inductive heater induces an electrical current in the body, wherein the body is heated by the induced electrical current; and

a driver capable of rotating the fiber producing device, wherein the fiber producing device is couplable to the driver through the coupling member; and

wherein the inductive heater is stationary with respect to the fiber producing device when the fiber producing device is rotated;

wherein, during use, rotation of the fiber producing device causes material in the body to be passed through one or more openings and ejected from one or more openings to produce microfibers and/or nanofibers; and

wherein the body comprises a channel, and wherein at least a portion of a coil of the inductive heater is positioned within the channel.

2. The system of claim 1 , further comprising a shield composed of an inductive transparent material and disposed in the channel.

3. The system of claim 1 , further comprising an insulative layer coupled to a bottom surface of the body.

4. The system of claim 1 , wherein the body has features that modify the path of the induced current flow through the body.

5. The system of claim 1 , wherein the shape of the body produces a homogenous distribution of current through the body.

6. A microfiber and/or nanofiber producing system comprising:

a fiber producing device comprising a body comprising one or more openings and a coupling member, wherein the body is configured to receive a material to be produced into a fiber;

an inductive heater positioned proximate to the fiber producing device such that, during use, the inductive heater induces an electrical current in the body, wherein the body is heated by the induced electrical current; and

a driver capable of rotating the fiber producing device, wherein the fiber producing device is couplable to the driver through the coupling member; and

wherein the inductive heater is stationary with respect to the fiber producing device when the fiber producing device is rotated;

wherein, during use, rotation of the fiber producing device causes material in the body to be passed through one or more openings and elected from one or more openings to produce microfibers and/or nanofibers; and

wherein the inductive heater comprises oppositely polarized magnets positioned on a surface of the body, and one or more permanent magnets electrically coupled to the polarized magnets, wherein rotation of the body causes a current to be induced in the body by the interaction of the polarized magnets with the one or more permanent magnets.

7. The system of claim 1 , wherein the body comprises one or more sidewalls together defining an internal cavity, wherein the one or more openings extend through at least one of the one or more sidewalls of the body, and wherein the inductive heater is radially inward of the sidewall of the body.

8. The system of claim 1 , wherein the driver is positioned above the fiber producing device, when the fiber producing device is coupled to the driver.

9. The system of claim 1 , wherein the fiber producing device is enclosed in a chamber, and wherein the environment inside the chamber is controllable.

10. A method of producing microfibers and/or nanofibers, comprising:

coupling a fiber producing device to a driver using a coupling member, the fiber producing device comprising a body comprising one or more openings;

placing material in the fiber producing device;

heating the body of the fiber producing device using an inductive heater, wherein the inductive heater is positioned proximate to the fiber producing device; and wherein the inductive heater induces an electrical current in the body, wherein the body is heated by the induced electrical current;

rotating the fiber producing device, wherein rotation of the fiber producing device causes material in the body to be passed through one or more openings to produce microfibers and/or nanofibers; and wherein the body is heated by the inductive heater during rotation of the fiber producing device; and

collecting at least a portion of the produced microfibers and/or nanofibers; and

wherein the coupling member further comprises a driving conduit coupled to the body of the fiber producing device, wherein the material delivery conduit is disposed within the driving conduit, and wherein the driving conduit rotates around the material delivery conduit during rotation of the fiber producing device.

11. The method of claim 10 , further comprising:

heating the material to a temperature sufficient to at least partially melt the material;

heating the fiber producing device with the inductive heater to a temperature at or near a temperature sufficient to at least partially melt the material; and

conveying the heated material into the heated fiber producing device.

12. The method of claim 10 , further comprising:

placing material in a fiber producing device; and

heating the fiber producing device with the inductive heater to a temperature at or near the temperature sufficient to at least partially melt the material disposed in the fiber producing device.

13. The method of claim 10 , further comprising mixing the material with a solvent to produce a mixture of the material in a solvent, and introducing the mixture into the fiber producing device.

14. The system of claim 7 , wherein the body and the openings rotate around the inductive heater.
