Patent ID: 7667369

Claim:
A system for sensing, comprising: a cantilever structure having a cantilever length extent and a cantilever width extent coupled to a substrate about at least one side of said cantilever, wherein said cantilever includes a piezoelectric section and has at least one acoustic wave device (AWD) on a portion of said cantilever , wherein an AWD length extent and an AWD width extent define an active acoustic region within said AWD, wherein at least one of said AWD length extent and said AWD width extent is less than at least one of said cantilever length extent and said cantilever width extent; and wherein a flexure of said cantilever produces flexure-frequency effects measurable by said AWD whose resonance is independent of the intrinsic resonant flexural frequency of said cantilever, wherein said AWD is a bulk-generated acoustic wave (BGAW) device and operates by at least one of energy-trapping and thickness-resonance modes.
