Abstract

Behavioral modeling of a new type of seismic sensor referred to as Differential Inductive Seismic (DIS) sensor for monitoring of seismic frequencies that are very close to the natural frequencies of buildings and other structures is presented in this paper. The model is validated by finite element method analysis using COMSOL Multiphysics 4.3a results show that the DIS sensor is highly selective to vibrations at resonance frequency and has good sensitivity and noise immunity. The sensor emulator and its readout circuit (ROC) are physically implemented on Texas Instruments (TI) ASLK PRO board. The ROC faithfully retrieves the single-tone seismic signal.
