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