Abstract: The application relates to a wind turbine component having an optical fiber sensor arranged to detect wind speed over the surface of the component. In one embodiment, the optical fiber sensor has a light loss portion that allows some of the light transmitted through the optical fiber to escape. The amount that the optical fiber bends in the air flow across the surface causes the effective surface area of the light loss portion to increase or decrease. With increased or decreased surface area of the light loss portion, more or less light is lost from the fiber. The intensity of the light transmitted in the fiber can therefore be used as a measure of the amount of bending, and therefore as a measure of the air flow's speed. In other embodiments, the optical fiber includes optical gratings, such as Fiber Bragg Gratings.

Abstract: A method for producing a modified graphene includes the steps of intercalating or inserting a mixture of intercalating agents in a spacing between interlayers of carbon substrates or between carbon substrates, whereby the binding force between the interlayers of the carbon substrates or between the carbon substrates is weakened; and then exfoliating the pretreated carbon substrates to form the modified graphene. With the environmental friendly purpose, the method according to the present invention is useful for reducing the total amount of a strong acid. Therefore, the amount of the generated oxygen-containing functional groups attached on the modified graphene is modulated to avoid defects and maintain a yield over 80%.

Abstract: The application relates to a wind turbine component 18 having an optical fibre sensor 10 arranged to detect the wind speed over the surface of the component. In one embodiment, the optical fibre sensor 10 has a light loss portion 15 that allows some of the light transmitted in the core 11 of the optical fibre to escape. The amount that the optical fibre bends in the air flow across the surface causes the effective surface area of the light loss portion 15 to increase or decrease. With increased or decreased surface area of the light loss portion, more or less light is lost from the fibre. The intensity of the light transmitted in the fibre can therefore be used as a measure of the amount of bending, and therefore as a measure of the air flow's speed. In other embodiments, the optical fibre can comprise optical gratings, such as Fibre Bragg Gratings or Long Period Gratings. Further embodiments use interferometry to measure the extension of the optical fibre.
