A method is provided to generate electrical current. The method includes creating a plurality of unitary masses each connected to one of a plurality of piezoceramic mass supports. The mass supports are electrically joined to a sheath. The method also includes removing material from the unitary masses to operably limit a mass vibration deflection. The sheath is attached to a vibrating body. The unitary masses are pre-tuned to match at least one natural frequency mode of the vibrating body. The unitary masses and the piezoceramic mass supports are induced to vibrate to generate the electrical current.

1. A method for generating electrical current, comprising:creating a plurality of unitary masses each connected to one of a plurality of piezoceramic mass supports;electrically joining the mass supports to a sheath;removing material from the unitary masses to operably limit a mass vibration deflection;attaching the sheath to a vibrating body;pre-tuning the unitary masses to match at least one natural frequency mode of the vibrating body; andgenerating the electrical current from vibration of the masses and the piezoceramic mass supports induced by the vibrating body.2. The method of claim 1, comprising pre-tuning the unitary masses by at least one of:varying a volume of the unitary masses;changing a height of the unitary masses; andcontrolling a spacing between the unitary masses.3. The method of claim 1, comprising varying a quantity of the unitary masses to operably vary the electrical current withdrawn.4. The method of claim 1, comprising:joining one of the unitary masses and one of the mass supports to operably form an element;electrically joining a plurality of the elements to operably form a cell unit; andconnecting a plurality of the cell units to operably form an array.5. The method of claim 4, comprising varying the electrical current by at least one of:changing a quantity of the elements per cell unit; andadjusting the plurality of the cell units per array.6. The method of claim 1, comprising generating the electrical current over an ambient temperature range varying between approximately ?60° centigrade to approximately 200° centigrade.7. The method of claim 1, comprising generating milliwatts of electrical current.8. A method for generating electrical current, comprising:creating a plurality of mass supports from a piezoceramic material;connecting a resist mass to the plurality of mass supports;separating the resist mass into a plurality of masses, each of the plurality of masses connected to one of the mass supports;electrically bonding the mass supports to a plurality of conductive elements of a sheath;removing material from the plurality of masses to operably limit a mass vibration deflection; andvibrating the plurality of masses to operably generate both an electrical current and a voltage measurable in milliwatts.9. The method of claim 8, further comprising connecting the conductive sheath to a vibrating body.
