A Mobile Sensor Network System for Sound and Vibration

Abstract

The smartphone has become a powerful computing device and is equipped with various sensors due to the advancement of sensor technology. In this study, we investigated whether the built-in accelerometer sensor of a smartphone can replace the traditional SHM measuring device, an accelerometer sensor. To compare and analyze the performance, we conducted a modal analysis using a small-sized PCB accelerometer and compared it with the traditional device on a steel frame specimen.
