Abstract

An artificial muscle including an internal electromechanically charged rod extending beyond two attach points. A plurality of mesh cylinders having a mesh cylinder top and a mesh cylinder bottom surrounding the charged rod. A fiber surrounding the mesh cylinders and mechanically attached to the mesh cylinders at an attachment spacing and wherein an electromagnetic source activates the artificial muscle through at least one microprocessor. The artificial muscle fiber may be nylon and the attach points may be titanium. The artificial muscle fiber may be coated with nylon. The artificial muscle fiber may contain a viscous fluid.

Claims (12)

1. An artificial muscle including:

an internal electromechanically charged rod moveably extending between a first attach point and a second attach point;

a plurality of mesh cylinders having a mesh cylinder top and a mesh cylinder bottom;

a plurality of fibers surrounding the mesh cylinders having a plurality of connectors mechanically connecting the fibers to the mesh cylinders and wherein

an electromagnetic source activates the artificial muscle through at least one microprocessor to electromechanically create a mesh cylinder movement.

2. The artificial muscle of claim 1 wherein the fibers are nylon and the attach points are titanium.

3. The artificial muscle of claim 2 wherein the fibers are weaved into a finger-trap configuration having a first end attached to a first point of attachment and a second end attached to a second point of attachment.

4. The artificial muscle of claim 1 wherein the fibers are coated with nylon.

5. The artificial muscle of claim 1 wherein the mesh cylinder movement is dampened by a viscous fluid contained around the mesh cylinders by the fibers.

6. The artificial muscle of claim 1 wherein the electromagnetic source is transmitted using induction-charging.

7. The artificial muscle of claim 1 wherein the plurality of connectors have an attach point spacing to control the degree of the mesh cylinder movement.

8. The artificial muscle of claim 1 wherein the mesh cylinders may surround the charged rod and move over a charge rod surface further extend or retract the artificial muscle.
