Abstract: A diaphragm for use in a transducer, the diaphragm including a flexible layer configured to deflect in response to changes in a differential pressure. The flexible layer includes a lattice grid. The lattice grid includes a first plurality of substantially elongate openings oriented along an axis and a second plurality of substantially elongate openings extending generally parallel to the axis. The second plurality of openings is substantially offset from the first plurality of openings in a direction substantially parallel to the axis. The first plurality of openings and the second plurality of openings define a first plurality of spaced apart grid beams extending between and substantially parallel to the axis and a second plurality of spaced apart grid beams extending substantially perpendicular to the axis. The second plurality of grid beams is configured to connect adjacent ones of the first plurality of grid beams.
