摘要

通过地震波检波器或昂贵的微机电系统加速度计，可以探测到地面上移动的人的振动，这些振动以地震波的形式引起土壤。我们提出了一种传感器节点，它使用低成本的弯曲模式压电加速度计，在其谐振频率附近工作，专门用于脚步声检测。

A prototype sensor node for footstep detection

Persons moving over ground can be detected from vibrations induced to soil in the form of seismic waves which are measured by geophones or expensive MEMS accelerometers. We are proposing a sensor node that uses a low-cost bending mode piezoelectric accelerometer, operating near its resonant frequency, specially designed for footstep detection.
