Microelectromechanical systems (MEMS)-based seismic sensors are highly sensitive devices used in geothermal exploration. These advanced sensors improve the quality and resolution of seismic data, enabling more accurate subsurface imaging and reservoir characterisation in complex urban environments.
The National Institute for Subatomic Physics Nikhef in the Netherlands, has successfully miniaturised anti-spring technology into a micro-scale accelerometer. This innovation in seismic sensors allows the combination of high-precision motion sensing, in a small form factor. In URGENT, this development will integrate the high-precision MEMS accelerometer and low-power internet-of-things (IoT) communication technology, both developed at INNO, into a small, QC-enabled, and sensitive seismic recording node ideal for deep geothermal exploration in urban environments.
