Abstract: Ultrasound transducer comprising an array of electro-acoustic micro-cells, a first and a second group of transducer elements arranged substantially along two directions (x, y), each element being defined by a group of micro-cells of the array, at least part of the micro-cells of each group being electrically interconnected by a first connection pattern having shape with main orientation along one of the two directions (x, y), characterized in that each group of micro-cells defining each element comprises micro-cells interconnected by further connection pattern or patterns having shape with main orientation along the other of the two directions (y, x).

Abstract: The invention concerns a capacitive ultrasonic transducer, comprising an external layer operating as an external plate, provided with electrode means, capable to vibrate, and a stiff substrate, in turn provided with electrode means, wherein it further comprises n levels, with n?2, interposed between the plate and the substrate, each level including a plurality of cavities, and m interface intermediate layers, capable to vibrate, among said n levels, with m=(n?1), the cavities of each one of said n levels being further defined by support means connected between faced surfaces of layers adjacent to said cavities, each one of said m intermediate layers being provided with electrode means, whereby the cavities of each level are interposed between a pair of electrode means belonging to either two adjacent intermediate layers or to an intermediate layer and to one out of the substrate and the plate.
