Abstract:
    An inertial force transducer (1) having an operative frequency range comprises a resonant element (2) having a frequency distribution of modes in the operative frequency range of the transducer and coupling means (4) for mounting the resonant element (2) to a site to which force is to be applied. The resonant element (2) is a piezoelectric device comprising a layer of piezoelectric material (6) and a substrate layer (3) on the layer of piezoelectric material (6). The substrate layer (3) has a region extending beyond the piezoelectric layer (6), with the coupling means mounted to the extended region (7) whereby the low frequency performance of the transducer (1) is extended.
