Our Mission

We are enabling smart load controlled wind turbines to operate between maximized power or maximized lifetime modes in a safe and controlled way according to market variables and business strategies.

We are on a mission to empower the deployment of rotor-load-controlled wind turbines that will pave the way for a far more competitive wind industry.

Why Choose Fibersail

Longer and more flexible blades need new solutions, able to monitor and control structural behavior from the root to the tip. Unlike current technologies, Fibersail focuses on the shape and curvature rather than the strains and stresses to achieve the highest accuracy and reliability for tip tower clearance and fatigue evolution.


The shape sensor is designed to suffer only 5% of its maximum threshold under harsh conditions, extending its lifetime for more than 25 years in operation.

Tip Positioning

Fibersail sensor measures shape and deformation for the full length of the blade, determining with high accuracy tip positioning and structural behavior for safer operations.


Low wavelength ranges and frequency rates required allow for the usage of modern and low-cost interrogation technologies for higher ROI.

Retrofitting Capability

Its unique design allows for simple retrofitting or replacement procedures of full length sensors for new business models.
