Patents by Inventor Joseph Anthony Micallef

Joseph Anthony Micallef has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Piezoelectric ultracapacitors
    Patent number: 8643253
    Abstract: As disclosed herein, multiple piezoelectric ultracapacitors may be coupled together in such a manner as to create an output voltage that is substantially the sum of their individual output voltages.
    Type: Grant
    Filed: October 31, 2010
    Date of Patent: February 4, 2014
    Inventor: Joseph Anthony Micallef
  • Piezoelectric device employing elastomer material
    Patent number: 7999447
    Abstract: An elastomeric piezoelectric ultracapacitor embodiment is also disclosed. A dielectric elastomer is a polymer that may be configured to operate in a “generator mode.” In generator mode the dielectric elastomer operates like a variable capacitor, and amplifies the energy of charge placed on a pair of compliant electrodes, formed on opposite sides of the elastomer, when the elastomer is in a compressed state. An elastomeric piezoelectric ultracapacitor employs generator mode techniques to further increase the power generation capabilities of an piezoelectric ultracapacitor.
