<p>A fluid sensing device such as a Shear Transverse Wave device (10) or a Love Wave device has a wave-trapping structure that provides tight surface trapping at transduction and sensing regions, but permits a deeper penetration of wave energy at the interface of a seal (32) with the wave-trapping structure. In the STW device, wave-trapping fingers (30, 40-50) are selectively varied in thickness, width or both to achieve the selective trapping. In an LW device, a wave-trapping plate is reduced in thickness at seal regions. <IMAGE></p> |
