At Innoseis ST, our technology was born in one of the most exacting sensing environments imaginable — gravitational-wave detection. Today, we bring that same scientific-grade precision into compact, scalable MEMS devices ready to power the next generation of research instrumentation, environmental sensing, and space-based measurement systems.
The Einstein Telescope (ET) is an upcoming underground observatory designed to detect gravitational waves. The Meuse-Rhine Euregion, which borders the Netherlands, Belgium, and Germany, is being considered as a possible location for the project. The project “Einstein Telescope Technologies” (ETT) is aimed at realizing the ET. Besides Innoseis ST, 11 other knowledge institutions and companies collaborate within the project to develop the required groundbreaking technologies, subsurface investigations, and technology spin-offs to other sectors. The project complements other research and work in projects such as ETpathfinder, E-TEST, and ET2SMEs.
As a core contributor to the Einstein Telescope Technologies (ETT) project, Innoseis Sensor Technologies is part of a 12-member consortium of leading universities, institutes, and deep-tech companies working to make the ET a reality.
Our role:
We are developing specialized MEMS accelerometers and gravity gradiometers to support both the construction and scientific mission of the ET. These sensors are designed to detect:
Seismic vibrations
Fluctuations in underground density
This sensing capability is essential for understanding the subsurface stability required by the ET — and equally valuable for applications such as:
CO₂ storage monitoring
Geothermal and mineral exploration
Environmental & civil engineering monitoring.
Our gravity gradiometer systems combine robust mechanical design with integrated signal processing electronics, resulting in devices that are:
Compact and lightweight
Deployable by a single operator
Optimized for both short-term measurements and long-term monitoring
Engineered for high durability with minimal failure points
Einstein Telescope-proven design: Trusted in one of Europe’s most advanced physics programs
Gravity gradiometer mechanics: Engineered for durability, fewer failure points, and long-term reliability
Compact & lightweight: Easy deployment — even by a single person
Built-in signal processing: Mechanics and electronics in one system, ready for field or lab
Innoseis ST sensors originally developed for gravitational-wave sensing now enable:
Quantum and photonics platforms
Cryogenic vibration isolation
Seismic vibration mapping for CO₂ and geothermal
Subsurface imaging in civil and environmental monitoring
Experimental payloads in space-based sensing systems
In 2021 Innoseis Sensor Technologies joined the initiative of Einstein Telescope Technologies (ETT) to further enhance the cutting-edge technologies and subsurface research related to the Einstein Telescope.
