About fiber optic sensing
Fiber optic sensors use a specialty fiber designed to measure strain and temperature at multiple points distributed along the length of a fiber of up to several kilometers. A read-out system, also referred to as an interrogator, captures the optical signal from the sensing fiber and correlates it to strain, temperature, and derived parameters such as pressure, tilt, displacement, vibration and even current and the presence of certain chemicals. 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 offset their major disadvantages of high cost of the interrogator. A step-change reduction in cost of fiber optic sensor interrogators will boost the utility and demand of fiber optic sensing in monitoring and process control even further.

About Structural Health Monitoring
Structural Health Monitoring (SHM) is a process in which engineering structures are continuously monitored throughout their lifetime for early signs of defects or 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 significant repair costs can be avoided. Furthermore, the data gathered from SHM increases knowledge about the structures being monitored and allows for better designs for such structures in the future. 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 and blast furnaces.

About Silicon Photonics
Silicon photonics is a technology whereby the functionality of optical components such as light sources, detectors, switches, wavelength (de-)multiplexers and filters can be integrated on a single chip. Having silicon as a base material, just like electronic chips, allows for using the well-established standard CMOS processes and manufacturing lines for production of these photonic chips. Decades of experience in the fabrication of electronic chips as well as a large installed base of semiconductor manufacturing capacity worldwide can be leveraged to scale up the production of low-cost optical chips. The sub-micron precision of microelectronic CMOS processes allows for silicon photonics chips to integrate a large variety of complex optical functions in a very small chip, enabling a wide variety of new applications and thereby driving a rapid expansion of the photonics industry. 

About Sentea
The company was incorporated in 2018 as a spin-off of the world-renowned Photonics Research Group of Ghent University and imec to commercialize more than a decade of research in silicon photonics and fiber optic sensing. Sentea’s mission is to make civil infrastructure safer and industrial assets more efficient by enabling widespread adoption of fiber optic sensors. Benefitting from the advantages of silicon photonics, Sentea offers fiber optic sensing interrogators that offer high accuracy, compactness 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.
