Fecha de publicación: 28/06/2018 Fuente: Wipo "Sensorization" A sensor 10 for measuring strain along a structure, comprising a sensor frame 20 holding a sensor element 30, where one edge of the sensor element 30 is connected to the sensor frame 20 and the other edges are unconnected from the sensor frame 20 thereby enabling deflection of the sensor element 30 relative to the sensor frame 20. A first spike 40 is connected to the sensorelement 30. The sensor further comprises a sensor target 50 and a displacement sensor 60, which is directed at the sensor target 50 for detecting displacement of the sensor element 30. At least one second spike 80 connected to a sensor base 65. The first and second spikes 40, 80 are made with a length enabling them to protrude from the sensor base 65 and to engage with the structure to be measured, and where the first spike 40 is running through the sensor base 65 without being in contact with it.
