Silicon photonics based fiber optic sensing allows for highly accurate, small, robust and cost-efficient structural health monitoring and process control
Ghent (Belgium) - September 7, 2018 – Ghent University (UGent) and imec today announced the incorporation of Sentea, a spin-off from their world leading Photonics Research Group. An initial 1.6 million Euro in funding was raised from Fidimec, Finindus, PMV and QBIC II and the founders. Sentea will develop and market advanced silicon photonics based fiber optic sensing solutions. These will be used to continuously monitor engineering structures for signs of damages that over time could lead to catastrophic failure, as well as to control industrial installations to maximize their efficiency.
According to the new market research report from MarketsandMarkets, the structural health monitoring market is estimated to grow from USD 1.48 billion in 2018 to USD 3.38 billion by 2023, at a CAGR of 17.93% between 2018 and 2023. The major factors driving the growth of the structural health monitoring market include concerns about catastrophic failure due to aging infrastructures in the developed countries, stringent government regulations pertaining to the sustainability of structures, and the superior benefits of structural health monitoring. Furthermore, the structural Health Monitoring Market for the Energy vertical is expected to grow at a rate of more than 20% from 2018-2023, owing to various applications such as wind turbines, nuclear power plants and hydropower plants.
“Integrating all optical functions into a single silicon photonics component will allow us to make highly accurate, small and robust fiber optic sensor interrogators. Silicon photonics is also very cost-effective, which makes fiber optic sensing affordable for a wide range of new markets and applications and facilitates universal and continues monitoring of structures”, commented Karsten Verhaegen, CEO of Sentea. “Key potential customers have expressed great interest in Sentea’s solutions, stating that better infrastructure lifetime management and process control makes them more competitive in their respective markets.”
“Sentea builds on state-of-the-art silicon photonics technology IP that has been developed at the Photonics Research Group of imec and the UGent for the past 20 years, a technology in which both organizations are perceived as world-leading,” stated Luc Van den hove, president and Chief Executive Officer at imec. “This firm technology base will provide Sentea a kick-start to develop its sensor technology that is answering an existing need in a broad range of market segments.”
To develop its first products and bring them to market, the company raised 1.6 million Euro in funding from a consortium of investors including Fidimec, Finindus, PMV and QBIC II.

Structural Health Monitoring (SHM) is a process in which engineering structures are continuously monitored throughout their lifetime for early signs of damages that over time could lead to catastrophic failure. By detecting any damage early on, and repairing or replacing the damaged part, catastrophic failure and the resulting downtime and huge repair costs can be avoided. A range of SHM solutions, such as fiber optic sensing, have found their way into engineering structures such as wind turbines, nuclear power plants, ships, trains, airplanes, buildings, bridges, dams, tunnels, heavy machinery, blast furnaces and so on.
Fiber optic sensing is a technology where the sensor itself is a specialty fiber designed such that it can sense pressure and temperature at multiple point along the length of the fiber. An interrogator device then captures the signal of the multiple sensing points in the fiber and interprets the signal into pressure, temperature or other derived parameters (e.g. acceleration or vibration). The inherent advantages of fiber optic sensors such as light weight, small size, passive, low attenuation, immunity to electromagnetic interference, wide bandwidth and environmental ruggedness are heavily used to offset their major disadvantages of high cost of the interrogator. Cost reduction of fiber optic sensor interrogators, together with new trends like IoT, big data and industry 4.0 will boost the utility and demand of fiber optic sensing in SHM and process control even further.
Silicon photonics allows for major cost savings and a significant increase in capabilities in developing and fabricating optical components. The ability to use standard CMOS manufacturing processes makes silicon photonics commercially very attractive. The sub-micron precision of these standard microelectronic CMOS processes allow for silicon photonics components to integrate a variety of optical functions in a very small chip that consumes far less power than traditional optical components. Decades of experience in making (electronic) chips from silicon as well as the installed base of (silicon) semiconductor manufacturing capacity can be leveraged to build highly integrated low-cost optical components for a variety of applications.
Sentea aspires to be a market leader in advanced fiber optical solutions for structural health and process monitoring. The company was incorporated in 2018 as a spin-off of the Photonics Research Group of Ghent University and imec to commercialize more than a decade of research in silicon photonics and fiber optic sensing. Benefitting from the advantages of silicon photonics, Sentea will develop and market fiber optic sensing interrogators that offer high accuracy, small size and advanced functionality, positioned for deployment in a wide range of applications and markets, hence enabling continuous monitoring of structural integrity to become the standard. Sentea is privately held by a consortium of investors including Fidimec, Finindus, PMV and QBIC II.
