  • Flexible and hybrid energy harvesting device combining piezoelectric and electrostatic conversions
    Patent number: 11870372
    Abstract: Disclosed are device implementations for a hybrid energy harvesting device and methods for harvesting mechanical energy from the ambient. The various device implementations utilize a combination of electrostatic energy conversion and piezoelectric energy conversion elements. The method simultaneously converts mechanical energy into electrical charge by electrostatic and piezoelectric energy harvesting. The devices include a piezoelectric harvester including a pair of electrodes and piezoelectric nanocomposite polymer, an electrostatic harvester including an electret film and a pair of electrostatic electrodes.
    Type: Grant
    Filed: June 11, 2019
    Date of Patent: January 9, 2024
    Assignee: THE JOHNS HOPKINS UNIVERSITY
    Inventors: James West, Ugur Erturun, Sung Hoon Kang, Adebayo Eisape
  • Push-pull electret transducer with controlled restoring force for low frequency microphones and energy harvesting
    Patent number: 11228844
    Abstract: Provided is an energy harvesting system, including: a first electrode; a second electrode; a non-metalized mono-charged electret diaphragm disposed between the first and second electrodes; a base; a spring extending between the base and the electret diaphragm; and a rod in communication with the electret diaphragm and for manipulating a position of the electret diaphragm relative to the first and second electrodes.
