Patent ID: 7658111

Claim:
A sensor subassembly, comprising; a mass; a crystal support structure; a BLSP ceramic, wherein the ceramic has a formula of [Bi 2 O 2 ][A m−1 B m−x M x O 3m+1 ], where m=2, A is a mono-, di-, or trivalent ion or a combination thereof, and B is a transition element, M is a donor dopant or combination of different dopants and x is the molar fraction of the dopant or the combinations of dopants, wherein M and x are chosen to modify piezoelectric charge coefficient and resistivity of the ceramic; the ceramic being mounted at the crystal support with a support member; a first electrode and a second electrode coupled to the ceramic; a first insulator positioned between the second electrode and the support member to isolate the ceramic and the crystal support, a second insulator positioned between the first electrode and the mass to insulate the ceramic and the mass.
