Abstract
A capacitive membrane ultrasound transducer is provided. Membranes or other microelectromechanical devices are provided in a 3-1 geometry, allowing application of an electric field substantially perpendicular to a range dimension. The membranes are on a plurality of different respective planes more parallel than perpendicular with each other, and the planes are more perpendicular than parallel with the faces of the elements or transducer.
