New FBG sensors for health monitoring

Technica, headquartered in Atlanta, Georgia, is launching a new family of Fiber Bragg Grating (FBG) sensor arrays in ultra-thin fibres for monitoring the structural health and integrity of composites.

Potential applications are in aerospace, high performance vehicles, marine vessels and energy during the design and optimization of the component, and while it is in operation.

For many advanced embedded-FBG sensing applications it has become necessary for the sensing fibres to have small dimensions, light weight, and low bend sensitivity in order to allow easy embedding with minimal compromise on the strength of the host materials, due to local stress concentrations.

To meet the growing needs of thin FBG sensors for advancing SHM in composite materials and a variety of other applications, Technica has developed thin single-mode fibre-based FBG sensors (T60) for a wide range of optical specifications and coating requirements. Fabricated directly in bare fibre and coated with acrylate, polyimide, or metal, the sensors are ultra-small and durable for use in tight spaces with minimal intrusion. When metalized (most commonly with Au), they can be encapsulated into hermetically sealed devices as well. The small-diameter fibres containing these FBGs have correspondingly smaller core, higher NA and higher cut-off wavelengths to significantly reduce macro-bending sensitivity, yet are said to work seamlessly with most optical sensing instruments worldwide.

Thin FBG sensors yield excellent wavelength to temperature and wavelength to strain linearity. Their small-size and fast response time make them useful and uniquely fitting for the in-process control of advanced composites manufacturing and real-time monitoring of high performance vehicles for space, air, water and land. New applications are emerging in the energy, medical and robotic sectors.
