An electric pulse generator includes a driver having an outer surface, a receiver, and one or more piezoelectric elements disposed between and in electrical contact with the driver and the receiver. The electric pulse generator further includes an explosive material disposed on the outer surface of the driver. A method of making an electrical pulse generator includes providing one or more piezoelectric elements, a driver, a receiver, and an explosive material and operably associating the explosive material with an outer surface of the driver. The method further includes electrically coupling the one or more piezoelectric elements between the driver and the receiver.

What is claimed is: 1. An electric pulse generator, comprising: a cylindrical driver having a first end, a second end, and an outer surface extending between the first end and the second end; a receiver; one or more piezoelectric elements disposed between and in electrical contact with the driver and the receiver; and an explosive material disposed on the outer surface of the driver. 2. The electric pulse generator according to claim 1, wherein the outer surface of the driver defines a groove and the explosive material is disposed in the groove. 3. The electric pulse generator according to claim 2, wherein the groove helically extends along the outer surface. 4. The electric pulse generator according to claim 1, wherein the driver has a generally right cylindrical form. 5. The electric pulse generator according to claim 1, wherein at least one of the driver and the receiver are bonded to the one or more piezoelectric elements by a conductive epoxy. 6. The electric pulse generator according to claim 1, wherein the one or more piezoelectric elements includes a plurality of piezoelectric elements bonded on facing surfaces by a conductive epoxy. 7. The electric pulse generator according to claim 1, wherein the explosive material comprises: at least one of cyclotrimethylene trinitramine, cyclotetramethylene tetranitramine, pentaerythritoltetranitrate, and trinitrotoluene. 8. The electric pulse generator according to claim 1, wherein the explosive material is detonating cord. 9. The electric pulse generator according to claim 1, wherein at least one of the one or more piezoelectric elements comprises: a ferroelectric material. 10. The electric pulse generator according to claim 9, wherein the ferroelectric material conforms to the formula ABO3, wherein A is a large, divalent metal ion and B is a tetravalent, metal ion. 11. The electric pulse generator according to claim 9, wherein the ferroelectric material comprises: at least one of lead zirconate and lead titanate. 12. The electric pulse generator according to claim 9, wherein the ferroelectric material comprises: a PbZrO3—PbTiO3 solid solution ceramic. 13. The electric pulse generator according to claim 1, wherein at least one of the one or more piezoelectric elements has an electrical permittivity within a range of about 1000∈0 to about 3000∈0. 14. The electric pulse generator according to claim 1, further comprising: a dielectric portion disposed between the driver and the receiver about the one or more piezoelectric elements. 15. The electric pulse generator according to claim 14, wherein the dielectric portion comprises: a material capable of holding off a voltage corresponding to about a breakdown voltage of the one or more piezoelectric elements. 16. The electric pulse generator, according to claim 14, wherein the dielectric portion comprises: one of a polyurethane, a polystyrene, an epoxy, a transformer oil, and a silicone rubber. 17. An electric pulse generator, comprising: a cylindrical driver having a first end, a second end, and an outer surface extending between the first end and the second end, the outer surface defining a substantially helical groove; a receiver; one or more ferroelectric elements disposed between and in electrical contact with the driver and the receiver; and a detonation cord disposed in the groove defined by the outer surface of the driver. 18. A method of making an electrical pulse generator, comprising: providing one or more piezoelectric elements, a cylindrical driver, a receiver, and an explosive material, the driver having a first end, a second end, and an outer surface extending between the first end and the second end; operably associating the explosive material with the outer surface of the driver; and electrically coupling the one or more piezoelectric elements between the driver and the receiver. 19. The method according to claim 18, wherein the step of operably associating the explosive material with the outer surface of the driver comprises: applying the explosive material in a helical form to the outer surface of the driver. 20. The method according to claim 19, wherein the step of operably associating the explosive material with the outer surface of the driver comprises: determining at least one of a pitch and a number of revolutions for the explosive material depending upon a desired output of the electrical pulse generator. 21. The method according to claim 18, further comprising: disposing a dielectric portion between the driver and the receiver about the one or more piezoelectric elements.
