Abstract
A sensing system responsive to a wavefield of acoustic or seismic signals. In one embodiment, the system includes a frame having a surface of tubular shape about which a layer of piezoelectric material can be positioned to extend along a first direction. A piezoelectric element is positioned under tension to apply a force against the frame, which tension increases signal response of the element.
