Seismic Instruments, 2011
The problems related to design of a portable seismic sensor working in a frequency range of 0.01–40 Hz are considered. Its main parts (pendulum, capacitive displacement transducer, magnetoelectric converter), structural diagram, and amplitude-frequency characteristic are described.

On the use of a seismic sensor as a seismic source
Geophysics, 2013ABSTRACT We investigated the use of seismic sensors as small seismic sources. A voltage signal is applied to a geophone that forces the mass within the geophone to move. The movement of the mass generates a seismic wavefield that was recorded with an array of geophones operating in the conventional sense. We observed higher-frequency (

Frequency-Selective Seismic Sensor
IEEE Transactions on Instrumentation and Measurement, 2012Recent trends in earthquake monitoring and prediction have focused on the monitoring of seismic frequencies that are very close to the natural frequencies of buildings and other structures, such as bridges. This paper introduces a new type of seismic sensor that is highly sensitive to vibrations at one specific frequency.

An inkjet printed seismic sensor
2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015In this paper an inkjet printed sensor in the mesoscale is presented with the aim to investigate its behavior as accelerometer in the low frequency domain typical of inertial stimuli coming from human caused and seismic phenomena.

Detecting the Seismic Event by the Electrodynamic Seismic Sensor
2020 XI International Conference on Electrical Power Drive Systems (ICEPDS), 2020Electrodynamic seismic sensors with two mechanic oscillation circuits could detect a ground vibration of two different objects with two different frequencies, for example, a human and a car. They don't need external power for their performance and have small overall dimensions, that's why they are attractive to use them in portable security or monitor ...

Imaging Seismic Tomography in Sensor Network
2013 IEEE International Conference on Distributed Computing in Sensor Systems, 2013Tomography imaging, applied to seismology, requires a new, decentralized approach if high resolution calculations are to be performed in a sensor network configuration. The real-time data retrieval from a network of large-amount wireless seismic nodes to a central server is virtually impossible due to the sheer data amount and resource limitations.

Seismic response of fiber optic seismic sensors
The Journal of the Acoustical Society of America, 2017Fiber-optic seismic sensors (FOSS) consist of an optical fiber connected to an optical interrogator, which is electro-optic instrumentation that injects pulses of coherent light into the fiber and receives and demodulates the returned signals. The optical fiber is usually contained within a protective cable.

The vertebrate ear as an exquisite seismic sensor
The Journal of the Acoustical Society of America, 1984The neotropical frog Leptodactylus albilabris exhibits the greatest sensitivity to substrate-borne vibrations (seismic stimuli) reported to date for any terrestrial animal. Nerve fibers from the source of this extraordinary sensitivity in the ear show clear stimulus-evoked modulations of their resting discharge rates in response to sinusoidal seismic ...
