Seismic-Acoustic Hybrid Sensor & Its Applications

Abstract : The need for instrumentation to gather seismic-acoustic signatures under unusual conditions requires the use of low cost, simple design, and robust sensors. In some instances, the sensors must adapt and mold to the environmental medium to provide proper coupling for data collection purposes. This paper explains how the idea of a hybrid seismic-acoustic sensor originated and initially implemented. Testing shows the device performs as a seismic and acoustic signature-gathering sensor. The data product from the hybrid sensor is similar to those sensors available through commercial sources. Further evolution of the hybrid sensor and additional commercial applications for the device are discussed.
