Abstract
A transducer () is provided where a membrane () is formed over a front substrate (); and a piezoelectric layer () is formed over the membrane () at an active portion () and peripheral portions located adjacent the active portion (). A patterned conductive layer including first and second electrodes () is formed over the piezoelectric layer (). Further, a back substrate structure is provided having supports () located at the peripheral portions adjacent the active portion (). The height () of the supports () is greater than a combined height () of the patterned piezoelectric layer and the patterned conductive layer. Many transducers may be connected to form an array, where a controller may be provided for controlling the array, such as steering a beam of the array, and processing signals received by the array, for presence or motion detection and/or imaging, for example.
