Abstract: A method for forming a sensing system responsive to a wavefield of acoustic or seismic signals. One embodiment includes providing a foil layer having first and second opposing surfaces and piezoelectric properties. The foil layer, configured as a sheet, is positioned about a frame surface which provides the foil layer a stable shape while permitting the sheet configuration of the foil layer to be responsive to a wavefield of seismic or acoustic energy. Coupling between the foil layer and the frame is so limited as to render direct coupling of the foil layer with signals of the wavefield the predominant means for stimulating the sensor element with seismic energy.

Abstract: A sensor system responsive to acoustic or seismic signals. One system includes a frame and a piezo-electric sensor element. The sensor element, responsive to a wavefield of seismic or acoustic energy, is positioned about the frame. Coupling between the sensor element and the frame is so limited as to render direct coupling of the sensor element with the wavefield the predominant means for stimulating the sensor element with seismic energy. Another system includes a frame and a cable element, responsive to a seismic or acoustic wavefield, extending about the frame. Coupling between the cable element and frame is so limited as to render direct coupling of the sensor element with the wavefield the predominant means for stimulating the sensor element with acoustic or seismic energy. The element may be coaxial cable or have piezo-electric properties to generate a charge differential measurable as a voltage between conductors.
