A body for holding a fiber optic strain sensor, a system including the body, and a method for determining strain in an object

A body for holding a fiber optic strain sensor, a system including the body and a method for determining strain in an object. Abstract The invention relates to a device and method for holding a strain sensor for determining strain in an object, the body of the device comprising a surface mountable frame, the frame being plate-shaped and including: at least two anchor portions for enabling attachment to a surface of the object, a strain sensitive region in an intermediate position between a first anchor portion and a second anchor portion of the at least two anchor portions, a sensor connection portion configured to hold at least one strain sensor for enabling attachment of the strain sensor to the frame in the strain sensitive region, and at least one elastic portion arranged in the strain sensitive region, the elastic portion being formed by a spring structure configured to modify a strain transmission from the object to the sensor connection portion of the frame. Preferably, device of the invention is adapted to hold a fiber optic strain sensor.
