    摘要: 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.

    摘要: 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.

    摘要: A method for deposition of an electrolyte material on a porous substrate in which a suspension of particles having a controlled surface charge and suitable for use as an electrolyte is formed and the porous substrate, which is made of an electrode material is immersed. A voltage is applied across the suspension between an electrode in contact with the suspension and the porous substrate, whereby at least a portion of the particles migrate toward the porous substrate and are deposited on the porous substrate.
