Abstract
An acoustic array of independently sensitive detecting elements is produced by locating a pattern of electrodes on a piezoelectric polymer film. Sensitivity of the film and a spaced away supporting structure are used to reduce artifacts caused by acoustic reflection in the supporting structure.
Claims10
A method of manufacturing an acoustic array comprising the steps of:
- (a) arranging an array of electrodes on a surface of a piezoelectric film in a plurality of rows;
- (b) attaching to each row of electrodes a first edge of a flexible carrier providing a plurality of conductive fingers extending across the rows and corresponding in number and location to the electrodes of a row;
- and
- (c) attaching the second edge of the flexible carrier to a set of terminals corresponding in number and location to the conductive fingers.
