Publication number: 20240153715Abstract: A method of fabricating a capacitor can include prelithiating a carbon material to form a first layer for the capacitor. The first layer including an anode or being an anode layer. A second layer can be positioned between the first layer and a third layer. The second layer can be or include a membrane and the third layer can be or include a cathode. The third layer can include activated carbon or utilize activated carbon as a cathode. Capacitors can be formed by use of this method and devices can utilize such capacitors. Instead of relying on lithium in metallic form, a carbon material can be prelithiated to include lithium ions therein to form an anode for the LIC that avoids use of lithium foil or lithium powder in the LIC and also avoid use of lithium in a metallic form in the LIC.Type: ApplicationFiled: February 9, 2022Publication date: May 9, 2024Inventors: Ramakrishnan Rajagopalan, Hossein Hamedi, Clive A.

Patent number: 7501743Abstract: A piezoelectric ultrasonic motor having 2-dimensional positioning movement includes a stator. The stator includes a piezoelectric ceramic bar and an electrode disposed on the bar. Each bar includes two wings that are separated by a predetermined angle to form a predetermined shape. A power source is used to apply a voltage to the stator to excite a bending mode vibration in the each of the wings, and the combined motion of the two wings produces an elliptical motion at a tip of the wing. A load is operatively connected to the stator, such that a portion of the load in contact with the stator is driven to move linearly through a frictional force between the load and the stator, due to the elliptical motion at the tip of the wing.Type: GrantFiled: April 27, 2007Date of Patent: March 10, 2009Assignee: The Penn State Research FoundationInventors: Kenji Uchino, Clive A.

Patent number: 6964718Abstract: Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.Type: GrantFiled: November 16, 2001Date of Patent: November 15, 2005Assignee: The Penn State Research FoundationInventors: Clive A.
