The SENVIDET consortium has created a working prototype sensor capable of measuring micro-vibrations to one billionth of a meter, safeguarding the Einstein Telescope and boosting chip manufacturing.

Milestones Achieved in Ultra-Sensitive Vibration Isolation

The SENVIDET consortium—short for Sensor Engineering for Noise and Vibration Isolation and Damping in the Einstein Telescope—has hit key technical benchmarks in October 2026 [2][4]. The initiative brings together small and medium-sized enterprises alongside research institutions: Somni Solutions, Innoseis Sensor Technologies, Quantified Air, Demcon HTS Delft, VSL National Metrology Institute, and the National Institute for Subatomic Physics (Nikhef) [2][3][4]. Somni Solutions successfully demonstrated the first working prototype of an optical inertial sensor [1][2][4]. Static calibration was conducted at VSL to verify its extreme sensitivity, followed by dynamic response tests at Nikhef that yielded favorable performance relative to traditional seismometers [2]. Concurrently, Nikhef commissioned the new ‘OmniSens 6D’ test facility in Amsterdam to validate the sensors under high-vacuum conditions [2][4].

How Photonics and Fiber Optics Power the Sensor Technology

At its core, this technological breakthrough relies on photonics and fiber-optic interferometry rather than electronic components placed inside sensitive telescope areas [4]. Developed by Somni Solutions with interferometric readout mechanisms designed by Quantified Air and rotation detection by Innoseis Sensor Technologies, the system utilizes fiber optics to measure physical displacements in two directions [4]. To protect hundreds of mirror towers inside the proposed Einstein Telescope from environmental disturbance, the sensors must achieve precision down to one billionth of a meter (1 nanometer) or one billionth of a degree (1 nanoradian) [2][4]. Existing commercial devices proved inadequate at addressing low-frequency seismic, thermal, and mechanical noise [1][2][3][4]. The SENVIDET prototype targets vibrations in the 1 Hz to 10 Hz range, with project coordinator Hedde van Hoorn, Senior Project Lead at Somni Solutions, noting a specific operational goal to measure below 3 Hz [2][4].

Cross-Industry Spillover: Semiconductor and Quantum Applications

While designed primarily to isolate gravitational wave detector mirrors, the underlying photonics platform offers significant dual-use potential across several high-tech industries [1][3][4]. The high level of vibration isolation and sub-nanometer accuracy is directly applicable to lithography and equipment manufacturing in the semiconductor industry, as well as control systems in quantum technology, nuclear fusion reactors, and regional seismic monitoring [1][2][3][4]. Financed through the Dutch National Growth Fund (Nationaal Groeifonds) and supported by regional development agency LIOF, the collaborative structure allows smaller Dutch firms to share the financial and development risks of fundamental research [1][2][3][4][5][6]. This framework transforms the big-science requirements of the Einstein Telescope into commercial opportunities for the broader Dutch high-tech ecosystem [1][3][4][6].

Industrial Scaling and Commercial Strategy

According to Albert van Dorssen, business developer for the Einstein Telescope Valorisation team, global evaluations by Nikhef confirmed that existing commercial market off-the-shelf systems failed to meet the rigorous isolation parameters needed for the facility [1][3][4]. By bringing together systems engineering expertise from Demcon HTS Delft and calibration standardisation from VSL, the consortium is bridging the gap between fundamental laboratory innovation and scalable industrial manufacturing [2][3][4]. Consortium lead Hedde van Hoorn highlighted that developing this state-of-the-art modular sensor technology in-house positions Dutch SMEs to mass-produce and supply high-precision optical sensor packages to global markets in the coming years [3][4].
