A piezoelectric ultracapacitor is disclosed capable of converting the kinetic energy of ordinary motion into an electrical potential. Multiple piezoelectric ultracapacitors may be configured together to provide an increased output voltage and various materials may advantageously be used. The piezoelectric ultracapacitor of the present invention may be used in various contexts, including power generation, switching and control and memory. An elastomeric piezoelectric ultracapacitor, along with methods of making and operating such a device, is also disclosed. The elastomeric piezoelectric ultracapacitor utilizes the voltage generation capabilities of a piezoelectric ultracapacitor and the generator mode operation of an elastomer actuator, combined and cooperating in novel ways, to provide improved energy generation capabilities.
An ultracapacitor comprising a piezoelectric material and an electrolyte between a first electrode and a second electrode, wherein said piezoelectric material is coupled to said electrodes so as to emit from said electrodes a voltage generated by said piezoelectric material.
A ultracapacitor comprising a plurality of electrodes, an electrolyte and a piezoelectric element located between said electrodes, wherein said piezoelectric element is configured to generate electrical current via said electrodes.
An ultracapacitor comprising first and second electrodes, a piezoelectric element and an electrolyte located between said electrodes, wherein said capacitor is configured to emit from said electrodes a voltage generated by said piezoelectric element.
