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.
