Portable digital seismometer [PDF]
Seismic Instruments, 2011 We have developed an autonomous portable digital seismometer for measurements in the field, in engineering constructions, and in hard-to-reach places. The seismometer is a monoblock including an SM-6 seismic receiver and digital seismic recorder. The SM-6 seismic receiver is a highly effective device for field work on investigating a microseismic wave ...

Bulletin of the Seismological Society of America, 1948
Abstract Theory and description are given of sensitive capacity-type seismometers having small size, eddy-current damping, and an undamped period of 0.23 second. The voltage output is taken to the grid of a cathode-follower tube within the instrument and is thereafter amplified.

Planetary Science Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al. , Knapmeyer-Endrun et al. , and Stahler et al. used recently detected marsquakes from the seismometer deployed during the InSight mission to map the interior of Mars (see the Perspective by Cottaar and Koelemeijer).

The Electrochemical Seismometer Based on a Novel Designed Sensing Electrode for Undersea Exploration
2019 20th International Conference on Solid-State Sensors, Actuators and Microsystems & Eurosensors XXXIII (TRANSDUCERS & EUROSENSORS XXXIII), 2019This paper developed a MEMS based electrochemical seismometer featured with a new structure of sensing electrodes. The sensing electrodes in this study can significantly increase the working areas of cathodes, and accurately control the geometries of the

A 3D Broadband Seismometer Array Experiment at the Homestake Mine
Seismological Research Letters, 2018Seismometer deployments are often confined to near the Earth’s surface for practical reasons, despite the clear advantages of deeper seismometer installations related to lower noise levels and more homogeneous conditions. Here, we describe a 3D broadband

NON-INTRUSIVE AND NON-CONTACT SLEEP MONITORING WITH SEISMOMETER
IEEE Global Conference on Signal and Information Processing, 2018Monitoring sleep quality and status is important to learn health condition for improvement and prevent sleep apnea. A bed-mounted seismometer system is proposed to monitor the heart and respiratory rates, and body movement and posture, during the sleep ...

Universal Piezoelectric Seismometer
Seismic Instruments, 2020A universal piezoelectric seismometer is proposed that can simultaneously record linear and angular accelerations through two separate channels. The operational principle of the seismometer and the features of its design are described; the mechanical and electric circuits are considered.
