ABSTRACT:
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.
