SYSTEM AND METHOD FOR DEPOSITING MATERIAL ON A PIEZOELECTRIC ARRAY
First Claim
1. A system for depositing material on a piezoelectric array of elements composed of electro-ceramic composite material comprising:
- a print head for depositing a material on the array;
means for moving said print head and the array with respect to each other; and
a computer system for controlling said means to move said print head and the array with respect to each other to locations along the array, and controlling said print head to dispense said material onto the array at the locations.

Abstract
A system having a print head for depositing material on a piezoelectric array, where the print head and array are moveable with respect to each other, and a computer for controlling movement of the print head and array with respect to each other to locations along the array, and controlling the print head to dispense the material onto the array at such locations. The print head deposits a pre-determined amount of material in one of dots, or in a line with movement of the print head and array with respect to each other. The system enables deposit of conductive material for electrical connections to array elements. Non-conductive polymer material may be deposited on the array before depositing conductive material to create barriers avoiding unintended connection of array elements by the conductive material. The system may also be used for fabricating a piezoelectric array by depositing electro-ceramic material.

20. A method for fabricating an electro-ceramic array comprising the steps of:
-
printing electro-ceramic material in dots upon a substrate at array locations to a height greater than a target thickness to provide elements of said array; sintering each of the elements of said array; applying filler material between and over the elements formed by the printing step; and grinding the array along the top thereof until the target array thickness upon the substrate is reached. - View Dependent Claims (21, 22, 23, 24)
