Abstract
Official abstract text for this publication.
Improved methods, and related systems and devices, for fabricating selectively patterned piezoelectric substrates suitable for use in a wide variety of systems and devices. A method can include providing a piezoelectric substrate having a protrusion of substrate material, depositing an electrically conductive coating so as to cover a portion of a side of the substrate and protrusion, and removing a portion of the coated protrusion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing electrodes on a piezoelectric actuator tube, the method comprising: providing the piezoelectric actuator tube, the piezoelectric actuator tube comprising a piezoelectric material, an interior lumen and a curved outer surface comprising one or more radially extending piezoelectric protrusions, each of said one or more radially extending piezoelectric protrusions having a thickness extending from the curved outer surface; depositing a c…
