The traditional geophone has been the industry standard for decades, and for good reason. Silicon Audio took what works and then added an optical component to increase sensitivity and performance, creating a new paradigm for seismic sensors. To understand how our optical seismometer works and what it means for data acquisition, watch this video.

current geophone (Figure 1). A MEMS accelerometer is a tiny silicon chip with a length of ~1 cm and weighing less than 1 g. A coil-based velocimeter is a cartridge with a length of 3 cm and weight of ~75 g. Within the MEMS, the residual displacement between the inertial mass and the frame is on the order of a few nanometers, while the motion

The first sensor package is a three-component 0.25g Silicon Audio accelerometer (EN, later renamed GN). The advantage of this instrument is that it has a broad frequency response and high dynamic Pankow et al. 5 range, but is temperature limited to 80 °C. The second sensor is a three component 15-Hz geophone (EH, later renamed GH).

The seismometer design is based on a commercial-off-the-shelf device manufactured by Silicon Audio Inc., and is a novel combination of a classic seismic geophone and a laser interferometer. Submicron-scale motions are recorded by the laser interferometer system. This allows for a small (<300gm), sensitive (1x10-8 m/s2/Hz1/2) broadband (0.01 ...

https://www.arxiv-vanity.com/papers/1810.09409/
In natural hazard warning systems fast decision making is vital to avoid catastrophes. Decision making at the edge of a wireless sensor network promises fast response times but is limited by the availability of energy, data transfer speed, processing and memory constraints. In this work we present a realization of a wireless sensor network for hazard monitoring based on an array …
