<p>A flexure-type accelerometer (20) includes a composite beam (70) mounted on a base (69). The beam includes a piezoelectric element (85) mounted on a substrate member (86). A plurality of scalloped recesses (99) extend into the substrate member from the surface (100) against which the element is mounted. These recesses also position the neutral axis of the beam between the element and the substrate member in the vicinity of weakened portions (115) in which flexure occurs. Hence, during flexure, the element is placed entirely in tension or compression, as appropriate.</p> |
