An electronic weapon with an installed deployment unit, from which at least one tethered electrode is launched, provides a stimulus current through a target to inhibit locomotion by the target. The wire tether, also called a filament, conducts the stimulus current. The one or more electrodes, according to various aspects of the present invention, perform one or more of the following functions in any combination: binding the filament to the electrode, deploying the filament from the deployment unit, coupling the electrode to the target, and distributing a current density with respect to a volume of target tissue. An electrode may include a spear comprising a material with integrated conductive and insulative substances (e.g., conductive fibers in insulative composite material) and a geometry to dissipate kinetic energy after impact with the target.

1. An electrode comprising: a body comprising a surface and a longitudinal axis, a rapidly expanding gas applies a force on the surface to impart a kinetic energy to the electrode to launch the electrode in a forward direction from an electronic weapon toward a human or animal target; anda spear comprising one or more resilient ribs, and a tip, the tip comprising a longitudinal axis, the spear mechanically coupled to a forward portion of the body; wherein: while the electrode travels toward the target, the longitudinal axis of the body and the longitudinal axis of the tip are coincident;upon impact of the electrode with the target: the tip penetrates tissue of the target to place the spear in or near target tissue;the one or more ribs flex to dissipate the kinetic energy;while the one or more ribs flex, the longitudinal axis of the tip is not coincident with the longitudinal axis of the body;after dissipating the kinetic energy, the one or more ribs cease to flex so that the longitudinal axis of the body is coincident with the longitudinal axis of the tip; andthe electrode provides a current from the electronic weapon through tissue of the target, the current for inhibiting voluntary movement by the target. 2. The electrode of claim 1 wherein the spear diffuses the current into the tissue. 3. The electrode of claim 1 wherein as the one or more ribs flex, a rear portion of the body rotates toward the target. 4. The electrode of claim 1 wherein: the spear is formed to flex more easily in a first plane than in a second plane; andan intersection of the first plane and the second plane defines an angle less than about 170 degrees. 5. The electrode of claim 4 wherein the first plane is about horizontal with respect to a vertical target. 6. A deployment unit for providing a current from a signal generator through tissue of a human or animal target, the current for inhibiting voluntary movement by the target, the deployment unit comprising: a housing;an interface that couples the housing to the signal generator, the interface for receiving the current;a filament that conducts the current, the filament stored in the housing prior to deployment, the filament coupled to the interface for receiving the current; andthe electrode of claim 1 mechanically coupled to the filament and stored in the housing prior to deployment. 7. The electrode of claim 1 wherein the spear further comprises a barb. 8. The electrode of claim 1 wherein the body and spear are formed of dissimilar composite materials. 9. An electrode comprising: a body comprising a surface, a rapidly expanding gas applies a force on the surface to impart a kinetic energy to the electrode to launch the electrode in a forward direction from an electronic weapon toward a human or animal target; anda spear comprising one or more resilient ribs, the spear having a first shape prior to launch, the spear mechanically coupled to a forward portion of the body; wherein: upon impact of the electrode with the target, the one or more ribs deform to dissipate the kinetic energy, deforming the one or more ribs causes the spear to acquire a second shape, the second shape different from the first shape;after dissipating the kinetic energy, the one or more ribs cease to deform and the spear returns to the first shape; andthe electrode provides a current from the electronic weapon through tissue of the target, the current for inhibiting voluntary movement by the target. 10. The electrode of claim 9 wherein the spear diffuses the current into the tissue. 11. The electrode of claim 9 wherein as the one or more ribs deform a rear portion of the body rotates toward the target. 12. The electrode of claim 9 wherein the first shape comprises a frustoconical shape. 13. The electrode of claim 9 wherein the second shape comprises a bent frustoconical shape. 14.

The electrode of claim 9 wherein the spear further comprises a barb. 16. An electrode comprising: a body comprising a surface and a central axis along a length of the body, a rapidly expanding gas applies a force on the surface to impart a kinetic energy to the electrode to launch the electrode in a forward direction from an electronic weapon toward a human or animal target; anda spear comprising one or more resilient ribs, and a tip, the tip comprising a central axis along a length of the tip, the spear mechanically coupled to a forward portion of the body; wherein: before impact, the central axis of the body is in line with the central axis of the tip;upon impact of the electrode with the target: the tip penetrates tissue of the target to place the spear in or near target tissue;the body moves with respect to the tip so that the central axis of the body is positioned at an angle to the central axis of the tip; andresponsive to movement of the body, the one or more ribs flex to dissipate the kinetic energy;after dissipating the kinetic energy, the one or more ribs cease to flex so that the body returns to its pre-launch position and the central axis of the body is substantially in line with the central axis of the tip; andthe electrode provides a current from the electronic weapon through tissue of the target, the current for inhibiting voluntary movement by the target. 17. The electrode of claim 16 wherein the spear diffuses the current into the tissue. 18. The electrode of claim 16 wherein the angle between the central axis of the body and the central axis of the spear increases until a portion of the body strikes the target thereby dissipating additional kinetic energy. 19. A deployment unit for providing a current from a signal generator through tissue of a human or animal target, the current for inhibiting voluntary movement by the target, the deployment unit comprising: a housing;an interface that couples the housing to the signal generator, the interface for receiving the current;a filament that conducts the current, the filament stored in the housing prior to deployment, the filament coupled to the interface for receiving the current; andthe electrode of claim 16 mechanically coupled to the filament and stored in the housing prior to deployment. 20. The electrode of claim 16 wherein the spear further comprises a barb.
