MEMS-Based Electrochemical Seismometer Relying on a CAC Integrated Three-Electrode Structure
This study developed a MEMS-based electrochemical seismometer relying on a cathode–anode–cathode (CAC) integrated three-electrode structure where two cathodes were positioned on two surfaces of a silicon wafer, while one anode was positioned on the ...

Study on the Equivalence Transformation between Blasting Vibration Velocity and Acceleration [PDF]
The evaluation of blasting vibrations primarily hinges on two physical quantities: velocity and acceleration. A significant challenge arises when attempting to reference the two types of vibration data in relation to one another, such as different types ...

A six degree-of-freedom fused silica seismometer: design and tests of a metal prototype [PDF]
Ground vibrations couple to the longitudinal and angular motion of the aLIGO test masses and limit the observatory sensitivity below 30 Hz. Novel inertial sensors have the potential to improve the aLIGO sensitivity in this band and simplify the lock ...

The Development of a New IFOG-Based 3C Rotational Seismometer
For many years, seismological research mainly focuses on translational ground motions due to the lack of appropriate sensors. However, because of the development of devices based on Sagnac effect, measuring rotational waves directly comes available.

Lab and Field Tests of a Low‐Cost 3‐Component Seismometer for Shallow Passive Seismic Applications
We performed laboratory tests and field surveys to evaluate the performance of a low‐cost 3‐component seismometer, consisting of three passive electromagnetic spring‐mass sensors, whose 4.5 Hz natural frequency is extended down to 0.5 Hz thanks to hyper ...

Validating a low-cost seismometer using a shaking table [PDF]
Ambient vibration measurement using a seismometer represent a non-invasive and non-destructive method for seismic-related studies. This method inhibits widespread applications, i.e., assessing site fundamental frequency, estimating bedrock level ...
